It's not just high intracranial pressure that's dangerous for our body. Intracranial pressure, or intracranial hypertension, is almost more serious🧠 This pathology is on the list of the most common diseases of the brain and is a hazardous disease that has a devastating effect on its structures. Pressure on the brain is exerted by the cerebrospinal fluid (cerebrospinal fluid) inside the ventricles of the brain. Intracranial hypertension develops due to a variety of causes. The most obvious example is a brain tumor. It displaces the hemispheres, thereby "squeezing" the cavities of the ventricles and the cerebrospinal fluid inside them. This causes an increase in pressure inside the ventricles. -

If the heart supplies blood to the whole body, what supplies it? No one thinks about this intriguing point. Well, except medical students😁 And the answer, in fact, is quite logical - the heart itself supplies itself with blood. What else... The first vessel that comes out of the heart is the aorta - at its very beginning, arteries branch off that go back and feed the heart. They are called coronary or coronary arteries. They wind around the heart like a crown or wreath - you can see in the animation. And just when the blood flow in these arteries stops or slows down a lot, the heart attack develops. -

Temporomandibular disorder An extremely unpleasant condition... Temporomandibular joints (TMJ) are the two joints that connect the lower jaw to the skull. The TMJs are some of the most complex joints in the body. Along with several muscles, they allow the lower jaw to move up and down, side to side, forward and backward. However, when the supporting structures of these joints (muscles, ligaments, disc, jawbone, temporal bone) are not synchronized in their movements - problems arise. And one such problem is temporomandibular disorder☝🏻 -

Diseases of unresponsive emotion Our bodies have one evolutionarily based response, "fight or flight". In stressful situations, our brains demand action from our bodies - fleeing from the problem or solving it. If such urges are suppressed, the aforementioned diseases can develop. A typical example of such suppression is resentment toward one's boss. The excitement in the brain that should have gone to the centers responsible for the work of the internal organs (vegetative centers) and to the motor centers (so that there is an opportunity to "beat or run") goes only to the vegetative centers. What happens is their excessive excitation - excessive release of noradrenaline and adrenaline, which leads to a sharp increase in blood pressure, tachycardia, spasm of blood vessels in the organs, increased formation of many hormones and so on. Diseases of unregulated emotions include arterial hypertension, atherosclerosis, stomach and 12 duodenal ulcers, hyperthyroidism, and more. -

Nice graphic of the anatomy of our human head and neck It depicts bones, muscles with tendons and even glands (only the parotid ones are visible, they are like yellowish "balls"). Here is plenty to explore - you can even feel the muscles in the picture on your own☝🏻

The brain zone preventing us from becoming rich! Yeah, the whole secret is just that😅 Cingular cortex - this area of the brain makes us anxious when our decisions don't match the "advice" of those around us. That is, it affects us the most during key decisions. And it is making the right choices in such situations that often allow people to get ahead in their career or business. Why did nature endow us with this "uncomfortable bark"? Because in the days of primitive life, the correct tactic was to act like everyone else in your tribe-then there was a better chance of survival. But now everything in the world has changed dramatically😉

Mitochondrion - the energy base of the entire cell After all, the main function of this organelle is to convert nutrients into useful energy using oxygen molecules. It is the mitochondria that synthesize ATP molecules. This process of energy generation within the cell is known as cellular respiration. -

Why is there a rupture of small blood vessels in general? Most commonly, these processes are manifested by nosebleeds☝🏻 So, the rupture of small vessels is more frequent when the elasticity of its wall is reduced. This happens with hypertension, atherosclerosis, diabetes mellitus, or even with the common hypovitaminosis due to impaired nutrition of the wall. Then the vessel cannot withstand the normal blood pressure and can burst even under the slightest load. -

The vascular "sacs" of the lungs are surrounded by tiny blood vessels. We are talking about the alveoli and the capillaries that wind around their walls. The alveoli and capillaries have very thin walls that allow oxygen to pass from the alveoli to the blood. The capillaries then connect to larger blood vessels, veins, which carry oxygenated blood from the lungs to the heart. -

One of the most important neurotransmitters in our body Glutamic acid (glutamate) is a neurotransmitter (impulse transmitter) in the human nervous system. If you look at the structure of our brain and the substances used by different nerve cells - glutamate is secreted by about 40% of all neurons. Such numbers put it in the lead. Through glutamate secretion in our brains, brain and spinal cord, basic information flows👇🏻 Vision, hearing, memory, and movement (before it reaches the muscles). Therefore, glutamic acid deserves special attention. -

Intervertebral disc herniation It occurs when part of the disc nucleus seems to push through a gap between neighboring vertebrae. The only time symptoms occur is when the herniated disc compresses a nerve☝🏻 -

Why do we observe patterns if squeeze or rub our closed eyes hard? Surely you’ve noticed such a strange phenomenon, and if not, try to do it now👀 These visual phenomena are called phosphenes. And nope, these are not "residual patterns of what one saw before closing one's eyes." These patterns are the result of excitation of nerve receptors. Pressures on the eyeball cause mechanical irritation of the retina and/or optic nerve. Since the visual centers of the brain are accustomed to interpreting information in only one way, they "draw" a picture before the eyes (most often in the form of divergent circles). -

The heart of cool athletes is sick! All because it has one pathological feature, characteristic of many serious heart diseases. Hypertrophy is a thickening of the muscle wall of the heart (myocardium). In athletes, it occurs compensatorily, so that the heart has more "power". After all, during physical activity, it is necessary to pump much larger volumes of blood. In addition, the volume of the heart chambers itself increases. Therefore, this condition sounds completely as eccentric hypertrophy. -

In a lifetime we lose about sixty bones Where do we "lose" them? Actually, not far at all. The fact is that some bones in the human body fuse together as we get older. In adults, the total number of bones ranges from 205 to 207, while infants have about 270 bones. The bones of the skull, for example, fuse together. That’s why newborns have "fontanelles," the place where the bones of the skull are still soft and not yet fused. The fusion process is also quite active in the bones of the pelvis and spine. -

At what temperature does a person start to freeze? Once again - no straightforward answer to the question😁 Human tissues begin to freeze at -0.5 degrees Celsius. And the freezing process can reach the stage of cell death (necrosis) even at this temperature. But from a medical point of view, it is the internal temperature of the body that matters most. Moderate hypothermia occurs at an internal temperature of 35 ° C. But as soon as it falls below 32 ° C - the body almost ceases to produce heat and the temperature begins to decline rapidly. Consciousness is lost at about 30 ° C, when the temperature drops below 28 ° C severely impaired heart function, and at an internal temperature of 20 ° C - the heart stops. -

What makes our skin so elastic and firm? After all, if it weren't for these qualities, something like this☝🏻 would be happening to our "surface". Collagen fibers are responsible for skin elasticity. They are inside the connective tissue, creating the so-called spring frame of the mattress. For elasticity are responsible, surprisingly, elastic fibers. They are located in the thickness of the skin at different angles, as if "tightening" the dermis and preventing the separation of its components.
