Scientists - anthropologists, psychologists and others - have accumulated great amount amazing discoveries. American anthropologist Dr. Stephen Juan, who teaches anthropology and social sciences at the University of Sydney, has published a series of books " Entertaining anatomy”, where he spoke about scientific facts, funny and useful, discovered not so long ago.
And science journalist Jennifer Ackerman, who writes for New York Times and National Geographic, which due to close communication with scientists she herself became practically a scientist, wrote “ Brief history human body." We took the most-most curious of their books.
1. Fatal seducers and dictators are born with teeth
Babies are usually born without teeth. This is what nature decreed - so that the mother does not reject the baby during feeding when she breastfeeds. But here's a fact: about one in two thousand babies is born with one erupted tooth. And then his feeding turns into a real torment for the mother. She automatically tries to feed him less often, less and generally wean him earlier. The baby just has to fight to eat.
From infancy, he develops a complex of the unaccepted into the world. And then in adulthood he is trying to win him over. Anthropologists have found that most of the world's dictatorial leaders were born with an erupted tooth. Julius Caesar, Hannibal, Napoleon, Mussolini, Hitler...
Pain from breastfeeding did not allow mothers to give these babies enough love. Therefore, such babies not only strive to conquer everyone and everything, but are also very jealous. They are afraid to lose love, and therefore don Juan of both sexes grow out of them, who want to be loved. more people. So they don't necessarily go into politics. They can go to the actors or just "rustle" other people's hearts in everyday life.
2. SALAMI CREATES A FEELING OF LOVE, AND SMALL DOSES OF ALCOHOL STIMULATES CREATIVITY
Alcohol consumption is very common in creative environments. And all why? It turns out that it stimulates the right hemisphere of the brain, which is responsible for imagination, visual images and non-standard creative moves. And on initial stage use contributes to creative discoveries.
A left hemisphere, responsible for logic and memory, associated with the responsibility and accuracy of details, plunges into a stupor. Therefore, an excess of alcohol creates special kind creativity is absolutely meaningless. Some scientists say that people with left-brain dominance even benefit from occasionally relaxing with a glass or two and turning on the right hemisphere.
It's also good to eat salami, which contains three times more phenylethylamine than chocolate. This is a mood-lifting substance, and with the participation of brain cells that are designed to work during love.
3. A TIGHT TIE AFFECTS EYE
Our eyes work harder than any other organ. To understand what kind of load they have, imagine that you need to walk 80 kilometers in a day. Yes, the legs will fall off from such an impossible task! But the eyes do not fall off. Meanwhile, the sharpness of our vision depends on a bunch of factors.
For example, a tight tie can affect your eyesight. American scientists in the course of many years of research found that in 67% of men, visual impairment is associated precisely with a tightly tightened collar. Because in this way the blood flow to the eyes is limited, it also affects blood pressure, which, in turn, also affects visual acuity.
And scientists advise to breathe deeply and evenly through the nose. This allows us to get more oxygen, which our eyes need so much. It has been proven that those who breathe correctly (through their nose and deeply) and do not smoke have better and longer vision.
4. IF YOU LAUGH A LOT, YOU DO NOT HAVE TO GO TO THE DOCTORS
We start laughing at 12 weeks of age. Laughter is highest form defensive reaction. Freud believed that laughter helps us cope with lustful thoughts. And Charles Darwin generally singled out an important role in evolutionary development for laughter. Like, relieves stress and helps restore mental stability. Without laughter, we would all have gone crazy a long time ago and would not have made any progress.
Dr. Norman Cousins discovered that laughter helps restore health. And that is why, for example, in America, laughter therapy rooms and chambers of fun are open in hospitals. How does it happen? From a biochemical point of view, laughter suppresses the formation of cortisol, which negatively affects the immune system.
Laughter increases metabolism, stimulates muscle tissue and releases a lot of positive hormones into the blood. Laughter prevents depression, heart disease and increases pain threshold. And, of course, in general, strengthens the immune system. There is even a saying that if you laugh every day, you won't need a doctor.
One recent study showed that laughter significantly increases the concentration of salivary immunoglobulin A (IgA). These are antibodies associated with resistance respiratory diseases upper respiratory tract. In general, perhaps one day the time will come when, instead of a doctor, they will send for a clown.
5. WILL SLEEP IN TWO PHASES, LIVE BECOME MORE HARMONIOUS
Does it happen that you wake up in the middle of the night and cannot fall asleep for an hour or two? You toss and turn and think that this is insomnia, and even struggle with it. But in fact, this is normal for the human body - a break in the middle of the night to wake up. Anthropologist Carol Wortman of Emory University has found that you need to sleep in two or even three phases.
Accepted in modern world The idea that you need to sleep continuously all night is wrong. For example, in cultures that are far from civilization, they still go to bed at sunset, then wake up somewhere at midnight and chat about everything for an hour or two, even dance, make love, laugh around the fire, meditate, pray and go back to sleep. .
But the electric light knocked our biological schedules off. But in the Middle Ages, even special brochures were published for the nobility, which told what to do during the night break for wakefulness. European doctors of those times, for example, recommended sleeping on the right side during the first sleep, and on the left side during the second sleep. This, in their opinion, improved digestion. Animals, by the way, sleep in several steps.
Thomas Ver, a psychiatrist from the United States, conducted an experiment. He put the subjects in natural conditions, without electricity, and began to follow their schedule. At first they slept continuously for 11 hours, and then their sleep also fell into two phases. They fell asleep for four hours, then woke up, stayed awake for two hours and fell asleep again for four hours.
After the experiment, the volunteers began to feel more harmonious, calmer, they improved Creative skills and fantasy. However, maybe this happened also because they lived in vivo and in total safety at all readiness. In any of us, I think, in such a situation, complete harmony would come in the soul.
WHAT ELSE SCIENTISTS DISCOVERED
You are healthy if you are able to understand another person
Psychiatrists and psychologists have invented many ways to find out if a person is healthy. Criteria mental health weight. But all tests have some flaws. And the main one is that you need to know the theory well in order to apply one or another more or less serious test in life. And any testing takes time. (Some stretch for the whole day.)
So, scientists have deduced one simple criterion for a mentally healthy person. It sounds both simple and complex at the same time: if you can accurately understand the other person's point of view, you are healthy.
Talents are revealed in the fifth ten
By the way, scientists also believe that the heyday of a person's intellectual life, as well as his psychological abilities, are fully capable of unfolding at the beginning of the fifth decade. At forty, the most interesting things in life are just beginning. Both in men and women.
You can die from lack of sleep and fame
Physiologically healthy man may die from lack of sleep. You just need not sleep for four days. Death from lack of sleep is preceded by complete disorientation and insanity. But, by the way, the fear of death is far from the worst. Only 31% of people are mortally afraid of death. And as many as 45% are scared to death of speaking in public. This is the so-called halophobia. So for almost half of the world's population, five minutes of fame can at least cause a severe neurosis.
Wounded in the heart don't always die
And more interesting facts about death. There is a widespread belief that if a person is stabbed in the heart, he will die. But it's not. Doctors testify that most of those wounded in the heart survive.
Also shorter people live longer. How to explain this, scientists do not yet know.
What you will not find in our body: an amazing zoo and mythical characters, mysterious plants and tools, colorful mosaic and a lot of edible things, geographical names and just funny words and objects. After all, anatomists use more than 6,000 (!) Terms to designate the most diverse nooks and crannies of our body.
Let's start with this phrase: “The entrance to the cave was guarded by an elderly gatekeeper, and there, inside, in the center of the labyrinth, in a crescent crevice, an amazing bird was sitting: a cockscomb, a wedge-shaped beak, fish scales; just fantastic!”
Amusing? But the most interesting thing is not so much in this phrase itself, but in the fact that it contains the names of several anatomical formations of our body.
Cave, scales, cockscomb ... Are these ordinary words can be anatomical terms? It turns out that they can, and besides, they are officially registered and accepted in all countries of the world. Human anatomy - the science of the structure of his body - is one of the most fascinating sections of biology and medicine. But also one of the most difficult. And anatomy is a beautiful scientific discipline. Her language is sweet-sounding Latin. Look at your palm. The palm is like a palm, and in Latin it is called the mysterious combination “palm manus” (palma manus). Even the place on which we sit is not called anything, but "regio glutealis" (regio glutealis).
Let's go back to our example. So where did the cave come from in the human body? In the meantime, there are even a few of them. One cave is part of the middle ear cavity, a special depression in the temporal bone, and the other is part of the stomach. By the way, the entrance to this cave, or rather, the exit from it, is really “guarded” by the gatekeeper. This is the name of the end part of the stomach, passing into the duodenum 12. Also, after all interesting name. The length of this gut is exactly a dozen cross-laid fingers. And the intestine itself is located in such a way that it forms a "horseshoe". However, this is a trifle compared to the cistern, which is also comfortably located in abdominal cavity. A chylous, or lacteal, cistern is the expansion of a large lymphatic vessel.
At the very beginning of the duodenum there is an extension called the bulb. That's really what there is more than enough in our body, so it's bulbs. They will be typed in a whole garden bed. They are in the duodenum, in the aorta, in the brain; hair follicles are known, it seems, to everyone, but only experts know about the bulb of the penis. What else is rich in our "anatomical menu"? Two apples: Adam's and eye (the first - on the neck, the second - it is clear where). There are also olives - a paired thickening of the brain stem. Not far from them are the almond-shaped and lenticular nuclei - special accumulations of the medulla.
"There are many things in the world, friend Horace ...". How can you remember this famous quote no matter how surprised. However, any organ of our body, any part of it, every nook and cranny of this body is truly remarkable. beautiful world in which we live without noticing it.
Among the many living beings that live on Earth, man is the most intelligent and most advanced in his development. The mind opens the way for us to self-knowledge, including understanding how our body works. Today, more than 6 billion people live on Earth. Each of them is unique in terms of personality, behavior, appearance, body proportions, manner of movement….
The voice is produced in the vocal cords of the larynx. The exhaled air contributes to their vibration and the appearance of sounds, which are then converted with the help of lips, teeth, tongue and palate into vowels and consonants of human speech. Sounds fly out of the mouth at a speed of 1200 km / h (340 m / s), the speech flow with very fast speech is 300 words per minute, and the propagation radius ...
The human body consists of more than 50 trillion. microscopic cells. They perform certain functions that ensure the coordinated work of the body. Liver cells (hepatocytes) form tissue. This tissue, together with other types of tissue, forms the liver organ. The liver and related organs are combined into the digestive system. The human body is arranged according to the hierarchical principle, i.e. as a sequence different levels difficulties,…
If the average duration of one sound (for example, the note “la”) without changing the tone and on one click for most people is 20-25 s, then the record is 55 s. Singing voices are classified according to their sound strength as follows: Ordinary voice - 80 dB Concert voice - 90 dB Opera voice - 100 dB Voice in a comic opera - 110 dB ...
There are 12 major systems in the human body. These are muscular, bone, nervous, endocrine, circulatory, lymphatic, digestive, respiratory, integumentary (skin, hair and nails), reproductive (male and female), excretory and immune systems. Each system is responsible for some one process or several processes necessary to sustain life. For example, the circulatory system, which includes the heart, blood vessels and blood, supplies all the cells of the body…
80 billion people have lived on Earth since the appearance of man (currently 5 billion people live, and 75 billion people have died). If you line up the skeletons of all the dead (7 skeletons per meter), then a line is formed that is 26 times the distance from the Earth to the Moon (10 million kilometers). Total weight there are 1275 billion of these skeletons...
There are 4 main types of tissues in our body. Epithelial tissue, composed of densely packed cells, covers the skin with a protective, waterproof surface layer and lines gastrointestinal tract. Connective tissue connects individual parts of the body and performs a supporting function. Its varieties are tendons, bone and cartilage tissue. Muscle consists of cells capable of contracting and thereby leading to ...
Funny terms that bear the names of places, objects or topics of everyday life, we divided into several groups. Nature, geography, architecture The aqueduct of Sylvius is the cavity of the midbrain. The tree of life is a gyrus on the surface of the cerebellum; Atlas (atlas) - the first cervical vertebra. “Strait”, or “gorge” [transl.] - the opening of the pelvis. “Slope” [trans.] of the foot. Spaces and cavities “Gastric cave” [transl.] – stomach cavity….
Our muscles weigh 28 kilograms! Any movement, from blinking to walking and running, is carried out with the help of muscles. Muscles are made up of cells that have unique ability shrink. Most muscles work in pairs as antagonists: when one contracts, the other relaxes. Biceps shoulder, contracting and shortening, bends the arm (the three-headed one relaxes), and when the three-headed one contracts (the two-headed one is relaxed), ...
Skeletal muscles Skeletal muscle cells (muscle fibers) are long and thin. They are formed by many parallel threads - myofibrils. Myofibrils also consist of filaments, or myofilaments, 2 types of proteins - actin and myosin - that give skeletal muscles a transverse striation. When in a muscle nerve fiber a signal comes from the brain, myofilaments slide towards each other, and muscle fibers ...
