Ever wondered what lies beneath your skin? X-rays can reveal just that. During an X-ray examination, a specially trained medical professional can see exactly what your bone structure looks like and interpret what this imaging reveals. The discovery of X-rays by Wilhelm Conrad Röntgen in 1895 was a milestone that satisfied the prevailing curiosity about the interior of the human body – it allows us to literally look beneath the skin. This article by Animus Medicus brings you closer to the world of X-rays and explains what to expect during an X-ray examination. This way, you can approach your next X-ray examination with ease and learn some fascinating things about X-ray technology. What are X-rays? X-rays are a form of electromagnetic radiation, similar to the light we see or the radio waves that transmit music and news. The difference lies in their wavelength: X-rays are much shorter, which gives them the ability to penetrate certain materials, such as our bodies. X-rays were discovered accidentally by the physicist Wilhelm Conrad Röntgen, who noticed a mysterious radiation that darkened photographic plates while experimenting with cathode ray tubes. Röntgen's discovery revolutionized physics on one hand and became an indispensable tool in medical diagnostics on the other. How an X-ray machine works The function of an X-ray machine is to create an image of something that lies beneath an opaque surface. In a classic medical X-ray machine, it essentially involves a tube that shoots electrons at a piece of metal. When the electrons hit, X-rays are produced and passed through the body being examined. Since different materials absorb the rays differently, an image is created on a detector or photographic plate. Bones appear white, soft tissues in shades of gray, and air appears black. Nowadays, digital X-ray techniques can directly convert these rays into images displayed on a screen. This modernization allows for immediate assessment of the imaging by the medical professional. X-ray explained: The procedure For those who have never experienced an X-ray examination, it might be hard to imagine. Here’s how an X-ray examination typically proceeds: Preparation: When it's your turn for the X-ray, you are often first taken to a regular treatment room before entering the room with the X-ray machine. The X-ray procedure is often briefly explained to you. You may be asked to remove certain clothing items, such as medical socks for foot injuries, and change into a gown. Personal items like anatomical jewelry and piercings should also be removed before the X-ray. Safety Measures: Although X-rays in high doses can be harmful, the amounts used in a typical X-ray examination are very low. Nevertheless, lead aprons or other protective measures are used to shield body parts that are not being examined. The X-ray: An X-ray is quick and painless. You will be asked to stand or lie still while the X-ray machine is briefly activated. Your position depends on the body part being imaged. The medical staff will help you position yourself to obtain the best possible image. It is crucial to stay still during the brief moment the image is taken to ensure clarity. After the X-ray: Once the images are taken, you can get dressed and leave the room. The entire procedure often takes only a few minutes, and the results are evaluated by a radiologist, who discusses the findings with you and your treating physician. Understanding anatomy through X-rays of bones What’s remarkable about X-rays is how they reveal the hidden structures of our bodies. They enable doctors to diagnose fractures, locate foreign objects, or assess the health of joints. X-rays are not limited to the human body; they also provide insights into the anatomy of animals, which is essential for veterinary diagnoses. X-ray imaging fascinates not only medical professionals but also the general public, as it makes visible what is invisible to the naked eye. The importance of X-rays for diagnosis X-rays are often the first step in the diagnostic process. Without them, a fracture might only be guessed. The anatomical images from an X-ray can reveal conditions that are not detectable through external examination methods. These include the presence of tumors, the extent of an infection, the presence of a bone injury, or the stage of a disease. Interpreting X-ray images requires expertise, as anomalies in bones and other parts of the human anatomy are not always easy to recognize and interpret. Your specialist will explain your X-ray results in detail and recommend further treatment. X-rays beyond medicine The application of X-rays is not limited to the medical field. Here are some other fascinating areas where X-rays are used: Art and Archaeology: Analysis of artworks and archaeological finds, revealing hidden layers and previous modifications, and estimating the age of bones based on their condition. Industry: Examination of material structures and detection of flaws. X-rays can identify cracks or air pockets, allowing for the sorting out of defective materials. Security Technology: Detection and prevention of hazards, such as at airports. Objects and clothing are scanned for dangerous items. Other Fields: Geology, astronomy, and many other areas also benefit from X-ray technology. The indispensable technology of X-rays X-ray machines and their function allow us to gain deep insights into the world around us and within us. This technology has revolutionized medical diagnostics and finds applications in many other areas. Interested in anatomy and medicine?

The Largest Bone in the Human Body: The Femur A healthy adult human has about 200 bones. The largest human bone is impressively strong and versatile. It can support your body weight and plays a central role in movement. We're talking about the thigh bone, also known as the femur. In this article, we introduce you to the femur and explain its significance as the largest bone in the human body. What is the Largest Bone in the Human Body? The femur, or thigh bone, is the longest and strongest bone in your body. It extends from the hip joint to the knee joint, forming the main part of your leg skeleton. Compared to other large bones, such as the tibia or the humerus, the femur stands out for its length and strength. The average femur measures about 50 cm and can withstand a weight of up to 1,000 kg. Anatomically, the femur is divided into three main parts. The first part is the shaft. Additionally, there are the proximal (closer to the body) and distal (farther from the body) sections. The proximal section includes the femoral head, which fits into the hip joint, and the greater trochanter, where important muscle attachments are located. The shaft of the femur is slightly curved to better distribute the load. The distal section includes the knee joint, the kneecap, and the tibia. Functions and Roles of the Largest Bone in the Human Body The femur performs numerous important functions as the largest bone in the human body. As the central bone of the leg, it supports the entire weight of your body, especially when standing and walking. The femur plays a key role in movement, acting as a lever that transfers the force of the leg muscles to the ground. Additionally, the femur plays an important role in connecting the hip and knee joints. Our hip joint anatomy allows for movements in multiple directions, while the knee joint anatomy is mainly responsible for flexion and extension movements. Both joints at the ends of the largest human bone are essential for activities such as running, jumping, and climbing stairs. Moreover, the femur provides stability and mobility for your entire body. Without a healthy femur, we are severely limited in everyday movements, and the risk of falls and injuries is increased. Development and Growth of the Femur The largest bone in the human body develops in the womb and grows into young adulthood. During childhood and adolescence, the femur undergoes several growth phases influenced by growth hormones and genetic factors. A balanced diet and regular physical activity are crucial for healthy bone growth. Depending on biological sex, the length and structure of the femur differ. Men typically have longer and more robust femurs than women, due to differences in sex hormones and physical demands. Medical Aspects and Common Issues with the Largest Bone While the femur is strong, it is not invulnerable. Breaks and fractures are common injuries caused by falls, accidents, or strong impacts. A femur fracture usually requires surgical treatment and a long rehabilitation period to restore full function. Osteoporosis can also become a health issue for the femur. This disease leads to a reduction in bone density, increasing the risk of fractures. Older people are particularly affected by osteoporosis, highlighting the importance of early diagnosis and treatment. Another risk to the largest human bone is osteoarthritis, a degenerative joint disease that can affect the femur and adjacent joints. It leads to pain, stiffness, and reduced mobility. Regular exercise and physiotherapy can help alleviate symptoms and maintain joint function. Evolutionary Significance of the Femur The femur has significantly evolved over the course of human evolution. In our early ancestors, the femur was shorter and less pronounced, as they primarily moved on all fours. With the development of upright walking, the femur became longer and stronger to efficiently support body weight. Compared to other mammals, interesting differences and similarities can be observed in femurs. For example, large land animals like elephants and horses also have long and robust femurs adapted to their size and weight. These evolutionary adaptations highlight the importance of the femur for movement and survival. Care and Maintenance of Bone Health To maintain the health of your femur, it is important to engage in regular physical activity and a balanced diet. Weight-bearing activities such as walking, running, and dancing strengthen the bones and promote bone density. Properly executed and targeted strength training can also be helpful in strengthening the muscles that support the femur. A diet rich in calcium and vitamin D is important for bone health. Dairy products and leafy green vegetables are good sources of calcium. Vitamin D, obtained through sunlight and certain foods, helps your body effectively use calcium and can improve bone health. Regular check-ups with an orthopedist can also help detect and treat potential problems early. Especially for older people, it is important to monitor bone density and take preventive measures if necessary. Conclusion on the Largest Human Bone The femur, as the largest human bone, is of central importance for your health and mobility. It supports your body weight, enables movement, and plays an important role in the function of the hip and knee joints.

The Smallest Bone in the Human Body: Essential Facts Introduction A healthy adult human has approximately 200 bones. The smallest of these is just a few millimeters in size and is located in the ear. It performs a variety of tasks in conjunction with the so-called stapedius muscle. As the smallest bone in the human body, the stapes can be affected by diseases that impair hearing. Therefore, it is advisable to regularly visit an ENT specialist. This article introduces the stapes and explains its significance as the smallest bone in the human body. The Smallest Bone in the Human Body is Located in the Ear The smallest bone in the human body is called the stapes due to its shape and is easily found in many anatomical images. It is located in the inner ear and, along with the malleus and incus, is responsible for transmitting sound to the eardrum. The stapes is only 3 mm in size, about half the size of a grain of rice. Despite its small size, it is relatively sturdy, making fractures or similar damage to the smallest bone in the human body quite rare. The stapes has always been significant in human evolution. It is also found in amphibians, reptiles, and birds, highlighting its importance. The connection to bony fish is particularly relevant in this context. The stapes forms during the embryonic stage and has two limbs. This shape is created as the stapes develops around the stapedial artery, making it the distinctive smallest bone in the human body. Functions of the Smallest Bone in the Human Body As the smallest bone in the human body, the stapes performs various functions. Primarily, it is responsible for transmitting vibrations that reach the inner ear to the eardrum. Without the stapes, significantly less sound would reach us, resulting in much weaker hearing. During sound transmission, the stapes, as the smallest bone in the human body, picks up vibrations from the air and transmits them to the cochlea and then to the eardrum. Here, a fluid called perilymph is present, which receives the sound. The stapes amplifies the sound vibrations by a factor of 20 to 30, which is necessary to prevent reflection losses when transitioning from air to fluid. Another function of the smallest bone in the human body is to protect the cochlea and the sensory cells within it. This ensures that sound transmission works perfectly over a long period. Due to this protective function, diseases affecting the stapes are particularly dangerous and should be diagnosed and treated promptly. The Smallest Bone in the Human Body and the Stapedius Muscle The smallest bone in the human body, the stapes, is connected to the stapedius muscle. This muscle leads directly to the stapes and can contract and relax, influencing the mobility of the ossicular chain. When exposed to sudden, high sound pressure, the stapedius muscle contracts, stiffening the ossicular chain. This function and the interplay between the stapes and the muscle provide a protective function for hearing. It ensures that sudden, high sound pressure does not damage the ear. Additionally, tympanometry can test the stapedius reflex. Doctors can assess how reliably the muscle works and the level of its protective function. They can also draw conclusions about the integrity of the eardrum and the nerve connections in the brainstem and the nerves in the ear and face. If you are interested in ear anatomy, check out our ENT image collection, perfect for learning or exploring. Common Diseases Related to the Smallest Bone in the Human Body Diseases affecting the smallest bone in the human body can have significant impacts on overall hearing. Therefore, individuals should promptly seek help from a specialist at the first sign of symptoms. One example is the sclerosis of the membrane, where the membrane becomes ossified, limiting the transmission of sound waves. As a result, sound impulses do not reach the eardrum as effectively, impairing hearing ability. The exact cause of such ossification remains unclear. It is believed that middle ear infections or similar conditions can lead to an effusion, causing fluid to enter and remain in the middle ear. This can lead to inflammation, adversely affecting the smallest bone in the human body. Fortunately, hearing loss caused by an effusion is often reversible. Removing the unwanted fluid or using an artificial stapes can improve hearing in some cases. Accurate diagnosis of the underlying condition is essential for effective treatment. Regular Visits to the ENT Specialist To maintain optimal hearing for as long as possible, it is advisable to regularly visit an ENT specialist. They can check the functionality of your hearing and ensure that no unwanted diseases or complications arise. This way, the stapes, as the smallest bone in the human body, remains well-protected. If symptoms appear, it is crucial to see an ENT specialist immediately. Early diagnosis can help identify and treat underlying conditions, ranging from a simple effusion to a tumor in the nasopharynx. The earlier the diagnosis, the better the chances of preventing diseases from affecting the stapes. For existing conditions, specialized ENT doctors with extensive experience in stapes surgeries are recommended. Conclusion: The Smallest Bone in the Human Body – Small but Mighty! The stapes may be the smallest bone in the human body, but it is of immense importance. Thanks to the stapes, we can hear as well as we do. Without it, sound transmission would be significantly weaker, and our hearing would be greatly diminished. Therefore, it is essential to care for the smallest bone in the human body through regular check-ups and appropriate treatments to ensure it remains healthy and functional.

In order to use knowledge or skills, it is necessary to access long-term memory. This stores facts, memories, and skills for minutes, years, or a lifetime, depending on their type. What long-term memory entails in detail, how it functions, and what strategies exist against poor long-term memory is explained in this article by Animus Medicus, the shop for anatomy images. What is Long-Term Memory? Long-term memory is a mechanism in the human brain. It is capable of storing information and skills over varying periods of time and making them retrievable. The information contained in long-term memory is extremely important for everyday tasks. A weak long-term memory can be managed to a certain extent through cognitive training. The Structure of Long-Term Memory Long-term memory is composed of two major areas: "declarative memory" and "non-declarative memory." Both are presented below: Declarative Memory Declarative memory is also referred to as knowledge memory. It is capable of storing knowledge, data, and facts as well as memories of events in such a way that they can be retrieved. The information stored here is explicit and can be reproduced verbatim. Two sub-areas of declarative memory are semantic and episodic memory. Semantic memory stores factual knowledge that is true independent of all people. This includes, for example, the fact that the Earth is a sphere. Episodic memory, on the other hand, stores facts about personal life. Thus, people are able to remember their first kiss.   Non-Declarative Memory Non-declarative memory is also referred to as behavioral memory. Here, learned sequences of actions or skills are stored. These enable a person, for example, to ride a bicycle. The information stored here is implicit and cannot be reproduced verbatim. Non-declarative memory is divided into three areas. Procedural memory contains all of a person's skills. Only through the information stored here are we able, for example, to swim. The second sub-area is priming. Here, various aspects are linked with individual pieces of information. What color are clouds? White. What color is snow? White. What does the cow drink? Milk. Because we have primed our memory for the color white, we think the cow must drink something white. But that is not the case; it drinks water. The third sub-area of non-declarative memory is conditioning. The best-known example of this is Pavlov's dog. Pavlov always rang a bell when he gave his dog something to eat. This led to the dog eventually producing saliva flow just from hearing the bell, without there being any food. If you would like to always have your anatomy image with you, we have just the thing for you: phone case with anatomy, for example with images of the heart, lungs, or brain.   Processes of Long-Term Memory Various processes take place in long-term memory. The first is learning. This means that information is stored in such a way that it does not remain only in short-term memory but moves into long-term memory. Only when this has happened do we have long-term access to such information. The second process consists of the sub-areas "remembering, retaining, and linking." People are now able to retain the information stored in long-term memory for the long term and recall it when needed. Furthermore, the stored information can be linked within it to derive new information or skills from it. Information that is not used, repeated, consolidated, and networked is deleted from long-term memory again.   Differences from Other Memory Areas There are different memory areas in the human brain, each fulfilling different tasks and possessing their own special characteristics and abilities. The three most important are presented in the following table: Ultra-Short-Term Memory Short-Term Memory Long-Term Memory Registers all sensory perceptions Also referred to as working memory Can in principle store an unlimited amount of data   Filtering of impressions   Stores information for about 30 seconds Depending on the type of learning, information is stored for minutes, years, or a lifetime Separation of important and unimportant Used for information that is not needed permanently stores and sorts incoming information so that we become consciously aware of it for the first time Stores factual knowledge, skills, and memories Forwarding of important impressions to short-term memory Forwards important things to long-term memory; unimportant things are overwritten Consists of various areas     Characterized by limited storage capacity Poor long-term memory can be attributed to circumstances (e.g., sleep deprivation) or illnesses   Indispensable for concentration and attention   Through training, the performance of long-term memory can be improved   Related to this topic, we have many different brain posters in our shop, which are excellent for giving as gifts but also for keeping yourself. Possible Causes of Poor Long-Term Memory Forgetting is fundamentally not a flaw of long-term memory in the brain, but a completely normal process. When information is not needed or needed too infrequently, we forget it. The same applies to skills we have acquired but do not practice regularly. However, there are various forms of forgetting that indicate poor long-term memory. There are some people who are unable to store and remember new information. This is called anterograde amnesia. Problems with retrieving information stored in long-term memory, on the other hand, are called retrograde amnesia. The opposite of this is hypermnesia, in which one involuntarily remembers things that are stored in long-term memory. There are many causes that can lead to poor long-term memory. These include, for example, sleep deprivation and high stress. Psychological stress, such as that caused by the death of loved ones, can also impair long-term memory. But even positive effects such as being in love occasionally have negative impacts on long-term memory. However, with long-lasting problems with long-term memory, illnesses can also be a cause. These include alcohol and drug addiction, but also Alzheimer's, dementia, or Parkinson's. Conclusion Weak long-term memory can be attributed to many different causes. If these are disease-related, not only the symptoms must be addressed, but the disease causes themselves. Against other problems, it is possible to improve long-term memory through a slight adjustment of one's life rhythm. Last but not least, it is advisable to regularly perform various memory exercises to maintain the performance of long-term memory. It is important to determine the individual causes of poor long-term memory and address them with individually tailored measures.

How is our lung actually structured?The two lobes of the paired lungs are further subdivided into lung lobes. The right lung consists of 3 lobes and 10 segments, the left only of 2 lobes and 9 segments (due to the position of the heart, space is somewhat limited here). As a result, the left lung has less space and has evolutionarily developed only 2 lobes.This brings with it a special feature. If you choke on something, for example, there is also a greater probability that the object will end up in the right lung. You can see this quite well in the photos. This is simply because the right bronchial branch runs somewhat vertically, as an extension of the trachea, and the left branch branches off at an angle, making it less likely that something will fall in here. Functionally, the air-conducting bronchial system is differentiated from the gas-exchanging alveoli.Bronchial system (air-conducting):The division of the lung into lobes and segments corresponds to that of the bronchial system. A lobar bronchus supplies a lung lobe with respiratory air, just as a lung segment is assigned according to the segmental bronchi.The bronchial tree splits approximately 20 times. Main, lobar, segmental, and subsegmental bronchi are distinguished. Accordingly, the division into lung wings, lobes, and segments also takes place.However, these sections only serve to transport air from the lung to the outside and vice versa. But not only that. These sections also have an important filtering function. Through various mechanisms, the inhaled air is filtered here so that pollutants, dirt, germs, and dust do not simply enter your lungs.Gas exchange:The respiratory bronchioles represent the starting point for gas exchange in the lungs. At their end, the alveolar duct (Ductus alveolaris), an accumulation of alveoli can be found (Sacculus alveolaris). The nearly 300 million alveoli in total offer an area of 100 m². Interalveolar septa separate the alveoli from each other.That sounds really crazy, right? But it gets even better. The alveoli have a great connection to your blood system and are surrounded by many tiny vessels. This is where the actual gas exchange takes place. The fresh inhaled air is full of oxygen, which your cells need for numerous metabolic processes. On the other hand, there is your blood in the vessels, which is enriched with CO2 and contains only little oxygen because your cells have already used it.Through this gradient and complicated biochemical processes, the CO2 now migrates into the respiratory air and is exchanged for the fresh O2. Your blood now has fresh oxygen again and can continue to supply your cells. You now exhale the old air and thereby breathe out the carbon dioxide. Ever heard of a pulmonary artery embolism? This can occur, for example, when a thrombus detaches from the leg and migrates up into the lung. This partially or completely closes pulmonary vessels. The result? You have filled alveoli, but without blood. As a result, gas exchange can no longer take place in these areas --> enlarged dead space. This leads to oxygen deficiency and shortness of breath because your body can no longer breathe out enough CO2 and take in O2.Smoking and the lungsDid you know? Just consuming one cigarette can shorten your lifespan by 7 minutes. With 20 cigarettes per day, this results in a reduction of lifespan by 35 days per year!Is tobacco consumption really worth it? Probably not. Moreover, smoking also represents a risk factor for various diseases and tumors.Pretty much any disease can arise from smoking. In this respect, it is extremely questionable why smoking is so promoted. Although... actually not, because money plays a major role here, of course, but that's a different topic now! That's it for the brief overview of the lungs. Did you like the article? Let me know and post your questions in the comments. You can also write in additions. :-)

7 Study Tips for University from a Medical Student In medical school, you often face a huge mountain of material, most of which you're supposed to know in a short time. This is often extremely discouraging and a single question pushes ahead of all others: "How am I supposed to get all of this into my head?" I've definitely been in this situation several times and know how overwhelmed and demotivated you can feel in such moments. That's why I'm happy to share a few tips with you here that have helped me conquer huge amounts of material while still taking care of my mental health; if you neglect it, you often quickly lose energy and stamina for studying. University is a marathon, not a sprint!   Tip #1 Divide the material into small parts It's best to start by roughly skimming through all your materials to estimate how many topics you can divide the material into and approximately how much scope each topic has. This way you can divide the big picture into smaller chunks that are much easier to tackle and that you can work through piece by piece. If you still don't know where to start: most textbooks have already thought about the order of topics, so: usually just start with the first topic, the rest almost always builds on it anyway.   Tip #2 Make a study plan For me personally, nothing works without a study plan. It brings structure to everyday life and gives you the feeling that you have your success in your hands and know exactly: if I follow the plan, I will definitely be done by the deadline. If possible: build in a few buffer days and some review days before the final deadline, this gives you extra security in case something comes up or concentration just isn't working one day. The study plan is also not a rigid structure. It can be modified at any time during execution. However, it's important that you maintain the rough framework so that you're sure to finish the material.   Tip #3 Quiz each other Studying together with classmates is immediately much more fun and it doesn't feel as awful as sitting alone in front of the book. Coordinate with 2-3 friends about when you're learning what, so you can discuss topics after a study day, explain uncertainties to each other, and especially quiz each other. This way you see where your strengths and weaknesses lie and can therefore firstly modify your study plan again and repeat the topics that didn't go so well, and secondly already catch your breath a bit when you see that studying has actually already achieved something in some places. Additionally, answering questions and discussing tremendously reinforces knowledge!   Tip #4 Visualize progress You so often have the feeling that you haven't accomplished anything yet and the mountain just won't get smaller. That's why it's important to visualize your progress and keep it in front of your eyes. The study plan worked well for me, for example, because I always checked off the topics I had completed. Every time I could check something off, it was a kind of mini-triumph and I knew that I had taken one more small step in the right direction. After a few days you then see how many topics you've already checked off and realize that all the work is actually achieving something.   Tip #5 Set study-free times Extremely important! Nobody can keep up 24/7 studying in the long run. Set a time at which you stop studying at the latest, take a break in the evening and do something that's fun for you and offers balance: exhaust yourself at the gym, go out for a nice meal with friends, or throw yourself on the couch with your friends and your favorite series. Sometimes take an afternoon off to do something pleasant. You don't need to feel guilty when you do something other than eating, sleeping, and studying. You can possibly pull through the latter for a few days, but in the long run it exhausts you extremely and study time is used much less efficiently, which then exhausts you even more, and so you get into a nasty vicious circle. After all, we're still humans and not machines, and humans can't work around the clock.   Tip #6 Don't lose sight of the big goal Especially in preclinical studies, it often happens that from all the memorizing you eventually think: "Why am I doing this to myself anyway?" You rarely have the feeling that you can actually concretely use all the knowledge you're stuffing into your head in the medical profession. Unfortunately, I can't currently judge whether you need the knowledge later. But what I can say is: no degree is easy and especially in medical school there's always a portion of ambition involved, because you feel like obstacles are constantly being placed in your way. So if you're in a phase where you think: What's the point of all this? Think about the final goal you want to achieve: becoming a doctor. On the way there you have to bite the bullet more often, but in the end it's worth it because you can practice the profession you really want to do. The colored boxes in the textbooks that establish clinical references always help me concretely. This way you can already become more fascinated with the topic. And if that doesn't help at all, here's the favorite saying of clinicians: After the Physikum everything gets better anyway! Tip #7 Enjoy the time Even if it should be stressful sometimes and you have to study a lot. You should try to enjoy every single second. Have fun with classmates, go out sometimes, or just do great things you've always wanted to do. In university you have so many freedoms as nowhere else. Enjoy the time when you're so young and energetic and don't take your studies toooo seriously.   How did you like the article? Were you able to take something away for yourself?

The human brain is unique in its anatomy. The brain consists of billions of nerve cells that are interconnected in complex ways. Nevertheless, the brain can be easily divided into different components and areas, some of which can be assigned specific functions. This article provides you with an overview of the anatomy of the human brain. Rough Division of the Brain into 5 Parts Human brain anatomy can be described in various ways. First, it makes sense to consider the brain (Encephalon) divided into five main regions. These five areas of the brain are recognizable to varying degrees in all vertebrates: Endbrain, often also called cerebrum (Telencephalon) Diencephalon (Diencephalon) Midbrain (Mesencephalon) Hindbrain (Metencephalon) Myelencephalon (Myelencephalon, also: medulla oblongata) The designation of these main regions is based on the simple brain anatomy of lower vertebrates, in which the regions lie tubularly one behind the other. The human brain is more complex in comparison, but these five brain parts are still clearly recognizable despite further evolutionary development. To give you an idea of the human brain, we will look more closely at the five brain regions mentioned below and describe further classification possibilities within brain anatomy. Endbrain and Diencephalon Form the Forebrain (Prosencephalon) The forebrain consists of the endbrain and the diencephalon. The large cortex of the endbrain (cerebral cortex, cortex cerebri) is particularly characteristic of human brain anatomy. Its characteristic convolutions (gyri) and grooves (sulci) result in a significantly enlarged surface area, allowing the volume to remain relatively small. The endbrain is composed of two hemispheres that are separated from each other by the fissure "Fissura longitudinalis cerebri". Deeper inside, however, they are connected by the so-called corpus callosum. In a frontal section of the brain, the gray and white matter of the hemispheres are visible. The image "Brain Structure in Section" depicts brain anatomy in such a section. The outer gray matter consists mainly of the cell bodies of nerve cells and the inner white matter consists of nerve fibers. The 4 Brain Lobes of the Endbrain Both hemispheres can each be divided into four lobes based on certain grooves: Frontal lobe (Lobus frontalis) Parietal lobe (Lobus parietalis) Occipital lobe (Lobus occipitalis) Temporal lobe (Lobus temporalis) As the name suggests, the frontal lobe is located at the front in the forehead area. The parietal lobe borders the frontal lobe from behind and extends to the occipital lobe located at the back of the head. The temporal lobe is located laterally below the parietal lobe. The position of the brain lobes corresponds to the similarly named cranial bones, as depicted in the image "Skull Bone Anatomy". Functional Areas of the Cortex The human cortex cerebri is particularly highly developed. It is responsible for characteristics that make humans what they are. Certain functions can be assigned to some areas of the cortex. For example, areas that process information from the sense of hearing are located in the temporal lobe. In the occipital lobe is the primary visual cortex, which handles part of visual information processing. The parietal lobe has areas of body perception that mediate skin, organs, muscles, and joints. The motor speech center and other motor areas are localized in the frontal lobe. There are also areas involved in personality formation. The Structure of the Diencephalon Between the hemispheres of the endbrain lies the diencephalon with the following structures: Thalamus Epithalamus with epiphysis Hypothalamus with neurohypophysis Subthalamus The thalamus serves as a switching center through which almost all information flowing to the cortex passes. It is also called the "gateway to consciousness". You can see the position of the thalamus in the image "Brain - Sagittal Section". This shows brain anatomy in sagittal section, that is in lateral view. The epithalamus sitting on top of the thalamus houses the pineal gland (epiphysis). This produces melatonin, known as the sleep hormone, and is thus involved in the sleep-wake rhythm. The hypothalamus lies below the thalamus and is connected to the pituitary gland (hypophysis). The pituitary gland, which is co-responsible for hormonal control, is divided into the posterior lobe (neurohypophysis) and anterior lobe (adenohypophysis). However, the adenohypophysis, which is made up of glandular cells, does not count as part of the brain. The hypothalamus controls, among other things, the autonomic nervous system, but is also involved in emotional life. The Limbic System Consists of Structures of the Forebrain The limbic system represents another functional division within brain anatomy. It includes brain structures that are responsible for controlling emotions. In addition, the limbic system performs important functions in learning and is in contact with the hypothalamus. It encases the corpus callosum, which connects the two hemispheres. The limbic system includes: Structures of the olfactory brain Amygdala Hippocampus Gyrus cinguli Gyrus parahippocampalis Due to the close relationship between the olfactory brain and the other structures of the limbic system, smells, memories, and emotions are often linked together. The amygdala plays an essential role in the emergence of fear, while the hippocampus is significant for learning processes and is involved in aggression and motivation behavior. The Anatomy of the Brainstem and Cerebellum The midbrain, the pons of the hindbrain, and the myelencephalon form the brainstem (Truncus cerebri). The nuclei of the cranial nerves, fiber bundles of the hypothalamus, and long pathways of nerve cells are located there. All three parts of the brainstem are connected to the cerebellum, which rests on the brainstem. The cerebellum is composed of the vermis (Vermis cerebelli) and also two hemispheres (Hemispheria cerebelli). Together with the pons, it forms the hindbrain and is responsible for balance, muscle tone, and coordination of muscle activity. With the myelencephalon, the brainstem finally transitions into the spinal cord, with the gray and white matter rearranging. From a developmental perspective, the brainstem is the oldest part of human brain anatomy.
