Here's what our liver looks like from the inside Its parenchyma (tissue) is pierced with blood vessels, because the main function of this organ is detoxification (blood purification). This purification is carried out by specialized liver cells - hepatocytes. They are shown in the animation as purple square cells. But what are the brown square cells next to them? These are also hepatocytes, but they have died. This happens most often in hepatitis, a group of inflammatory liver diseases. Hepatitis viruses and alcoholism are the most common causes. -

Genital nerve Oh yeah, there is a separate nerve for this part of our body! The genital nerve is the largest part of the genital plexus (network of nerves), located behind the sacrospinous ligament, next to the coccyx. The nerve runs from the sacral plexus, through the genital canal, the perineum, and the gluteal region. In short and simple, in the pelvis. The condition, known as genital neuralgia, can cause both urinary incontinence and anal incontinence. Other symptoms include chronic constipation, rectal pain and sexual dysfunction. The situation is extremely uncomfortable...

Sebaceous glands and heredity are the main causes of acne Acne occurs with a hormonal shift during puberty or pregnancy and with stress, other factors are not proven. Certainly, it is most often teenagers who are affected by this problem. The cause of the appearance of acne is considered during puberty, an increase in sebum production as a result of a hormonal surge. What is sebum? And this is the secret of the sebaceous glands☝🏻 Other possible causes include clogging of the sebaceous ducts with skin care products and infestation with parasitic mites of the genus glandularis. -

One of the worst pains Migraine. And in the context of headaches, it "stands apart". And this is not just pain - a migraine is an independent disease. But why then does this pathology arise? For quite a long time, medicine had no answer to this question, but nothing stands still - now the cause is known. It's about the increased excitability of nerve cells. They make the vessels dilate, to which the pain receptors of the vessels themselves react. And a strong unilateral pulsating pain appears, which is exactly how migraine manifests itself. -

Why does alcohol impair coordination? All because it destroys brain cells - hundreds of neurons per minute! And anyway, that's it... Obviously, just kidding - it can only accumulate with the effects of frequent alcohol consumption. The reason is that, when alcohol enters the bloodstream, it destroys the walls of the red blood cells. They become loose, sticky, and if there are a lot of such red blood cells, it contributes to their adhesion and clot formation. This leads to the death of brain cells. As these clots clog the small vessels of the brain☝🏻 The wobbly gait in non-alcoholics is just a consequence of the effect of ethanol on the cerebellum. It blocks the connection between its neurons and the brain. And it is the cerebellum that is responsible for movement coordination - that's why drunks are so clumsy. -

Why do cramps occur? Mainly, they arise when the metabolic processes are disturbed, which leads to a decrease in the amount of ATP. If there is a lack of ATP, muscles are unable to relax on their own, and a convulsive contraction occurs. It usually lasts a few seconds, sometimes a few minutes. What is the underlying cause? There are actually many of them. Stress, excessive muscle strain, dehydration, lack of Mg, Ca, vitamin D3 and some other micronutrients. And at night it can be triggered by an uncomfortable posture. Most often cramps occur in the lower extremities, and especially in the calf muscle. But a cramp in the abdominal muscles or a short spasm (as in the animation) is quite rare -

The brain floats in our skull Almost levitating🧠 This is because the cerebrospinal fluid serves as a cushion for the brain. Why is there such an anatomical design? It protects the brain from the impact, gives it some plasticity. After all, during the collision of the skull with some object, it moves inside - this can negate the traumatic effect of not too strong blow. But if the brain were tight to the cranium - the brain injury would occur with much less traumatic force. -

What makes bones ductile and strong? Let's go in order👇🏻 Organic substances (the main one is ossein) and fibers are responsible for bone elasticity and flexibility. Children feature a higher proportion of organic substances in their bones than adults, so they are more flexible. But for hardness are responsible inorganic substances - mainly salts of calcium, phosphorus and magnesium. The very structure of the bone plates is also responsible for density. Naturally, both of these characteristics work in tandem, due to which bones become the perfect "foundation" of our body🦴 -

"Burned out at work” Unfortunately, the phrase is familiar to many people... It describes a condition called emotional burnout. Such a syndrome occurs due to chronic stress in the workplace. But how does this pathological condition manifest itself at the level of physiology🤔 Of course, it has its morphological manifestations at the level of the brain! It was found out that in people with long emotional burnout the frontal cortex - a region of the brain necessary for cognitive processes - begins to thin. Along with it, the volume of gray matter decreases in the hippocampus, which participates in the formation of emotions and memory consolidation. In addition, the amount of cortisol produced decreases. This is the stress hormone, which is responsible for energy storage in the body and is involved in the synthesis of cellular enzymes⚡️ By the way, that’s why emotional burnout leads to the development of diabetes and obesity. -

Why can't you look at the welding? You've heard this advice many times, haven't you? And for good reason. The radiation of the electric arc is really detrimental to our eyes. Yes, we do not feel this effect, but this is only because this area has no pain receptors🙌🏻 Infrared and ultraviolet, coming in a range invisible to the eye, is the most damaging. This radiation can cause serious damage to the retina, cornea, and lens. -

Oh, that ankle... The word "twisted" seems to be one of its favorite words. If the circumstances are too unfortunate, the situation can go as far as tearing ligaments☝🏻 Sadly, many athletes are familiar with this. But there is another less dangerous, but extremely discomforting condition - chronic instability of the ankle joint. This pathology causes ankle ligaments to be sprained more than once in a fairly short time interval. Instability of the ankle joint is mainly due to the fact that the subtalar joint appears to be excessively mobile. People with clubfoot and flat feet, which cause the lateral ligament to deviate in axial rotation during leg movements, are susceptible to injury. -

How does oxygen from the air get into the blood and organs? Where exactly in the lungs does this happen? It happens in the alveoli☝🏻 The alveoli are the final part of the respiratory apparatus - they look like bubbles or sacs. Through the entire bronchial tree, air enters them. So, the little capillaries that permeate these alveoli are just the ones responsible for gas exchange. When you breathe in, the arterial blood "comes in" and enriches with oxygen, carrying it to the rest of the body. And when we exhale, the venous blood gives back the carbon dioxide "collected" in the body, getting rid of it. -

A process that doesn't halt for a second. In fact, there are quite a fews in our body.😅 However, today is about mitosis. It is the process of a cell dividing to form two identical, genetically identical cells. Mitosis is the main tool of any organism's life - it is responsible for cell growth, development, movement, and regeneration. What happens if mistakes occur during this process? Fails in replication and mitosis lead to the formation of mutant clones. -

There are special kinds of drugs with their effects artificially "stretched out" Depot forms and retarded forms. Retarded forms (from Latin retardo - to slow down) ensure that the active substance is stored in the body and then slowly enters the bloodstream. They are almost like "regular" drugs, but their effect develops slowly. Depot forms (from Latin dēpositum, "storehouse") work in a similar way. But they can be used a small number of times and often act as implants. Thus depo-forms create a stock that is slowly released. It is the retarded forms that are more common. You may even find a drug with this prefix in your medicine cabinet☝🏻
