Amazing facts about the language of the human body. Interesting facts about the human senses

Humans have five main senses: sight, hearing, taste, smell and touch. Each of these organs has its own complex structure and functions. Knowing how the body and its sense organs are built is not only interesting, but also useful, if any violations occur, you will know what it is connected with.

____________________________

Organ 1: Eyes

With the help of the eyes, a person sees, which is undoubtedly very important, because without vision it is extremely difficult to have. Through the eyes, a person receives the largest amount of information from the outside world.

Description of the building

The eye consists of several important parts, namely:

The part that receives visual information is peripheral.
The paths along which the signal about what he saw moves: the optic nerves, the tract and the decussation.
Under cortical centers located in the brain.
Visual cortical centers located in the occipital lobes of the brain.

The peripheral part of the eye consists of:

1. Outer part:

The sclera is the membrane of the eye that is made up of connective tissue. It gives the eye shape, muscles are attached to it. Its functions are support and protection eyeball.
The pupil is the hole through which we see. Light passes through it and, depending on its intensity, the pupil narrows or expands reflexively.
The anterior chamber is the moisture-filled space in front of the pupil that protects the eye.
The iris is a movable thin diaphragm around the pupil that does not transmit light and contains pigment, due to which a person has a colored pupil. Due to the muscles of the diaphragm, a change in the size of the pupil occurs.
The cornea is the convex outer part of the eye. Its important function is light refraction, and the cells in it are arranged in optical order, which allows light rays to pass through without distorting.
The conjunctiva is the mucous membrane of the eye and eyelids that secretes tears. The function of the conjunctiva is to protect and moisturize the eye.
Eyelids - skin folds around the eye, which distribute tear fluid throughout the eye and protect it from the ingress of various objects.
The orbit is the bony receptacle of the eyeball, which also contains blood vessels, muscles and nerves.

2. Interior:

The vitreous body is the largest part of the eye, consisting of hyaluronic acid and water. Collagen fibers pass through it. Functions - refraction of incoming light, maintaining the shape of the eye and turgor.
The lens is a transparent body without vessels, located behind the pupil in front of the vitreous body. It has the shape of a lens and is powered by intraocular fluid. The main function is the focus of vision.
The retina is a membrane consisting of many layers. It consists of photoreceptors - cones and rods. Cones are responsible for the perception of an object - its color and shape. Rods are responsible for the ability of a person to see in the light, twilight or in the dark.

3. Lacrimal apparatus of the eye:

lacrimal gland;
lacrimal ducts;
nasolacrimal duct;
lacrimal sac.

4. The muscular apparatus of the eye:

Functions

The main functions of the eye are:

color perception;
peripheral vision;
light perception;
stereoscopic vision;
objective (central) vision.

The eyes are a complex optical system that transmits image information to the brain and serves the life support of a person.

Interesting Facts

Women have better lateral (peripheral) vision than men.
The human eye can distinguish up to 500 shades of gray.
Each person has an individual iris, and therefore it can be used together with fingerprints for identification.
The eyelids close automatically when sneezing, this reflex property helps to avoid rupture of the eye capillaries.
It is impossible to perform a complete eye transplant, since restoring optic nerve and endings that communicate with the brain are beyond the power.
In 1 percent of people on the planet, the color of the iris of the right and left eyes is different.
There are 150 eyelashes on the upper and lower eyelids of a person.
Surprisingly, in 12 hours a person makes about 25 minutes of blinking.
The least common are people with in green eyes, there are only 2 percent of the world's population.

Organ 2: Ear

The ear has the ability to perceive sounds, which is important for communicating with people around.

Description of the building

The ear consists of a central and peripheral part. The central part includes:

nerve fibers that terminate in the temporal lobes of the cerebral cortex.

The peripheral part of the ear consists of:

1. Outer ear - collects sound, which then enters ear canal to eardrum. The outer ear includes:

The auricle is a cartilaginous plate that is attached to the temporal part of the head with muscles and ligaments. There is no cartilage on the earlobe.
The ear canal is a gap with a small gap, which acts as a sound amplifier. Contains sulfur and sebaceous glands. If a person is hard of hearing, he puts his palms to the auricle to amplify the sound.
The eardrum is a thin sheet that separates the ear canal from the middle ear. Sound vibrations cause the eardrum to vibrate at the same frequency. As we age, the eardrum becomes thicker and rougher, making it harder for older people to hear.

2. Middle ear - air cavities that connect to the nasopharynx. The middle ear consists of:

3. inner ear- located in temporal bone bone formation.

It is a complex system of bone canals and consists of:
The vestibule is the main part of the bony labyrinth.
The semicircular canals are responsible for the perception of sound.
Bone cochlea - consists of a channel with three passages, in which there is a liquid that conducts sound vibrations.
vestibular analyzer that controls muscle tone, balance and position of the body in space.

Functions

The main functions of the ear are:

Interesting Facts

The Eustachian tube protects the eardrum from destruction due to a sharp drop or increase in blood pressure, for example, in the mountains, on an airplane, while diving.
Ears grow throughout a person's life.
When a person needs to hear another through extraneous noise, such as music, he usually turns to the interlocutor with his right ear.
In wrestlers and rugby players, the ear often resembles a cauliflower, as its cartilage is constantly damaged and it has no bones to repair.
The ears are a self-cleaning organ. The pores produce wax inside the ear, and small cilia push it out of the ear.
The ear for music is better developed among peoples who have a more melodic language.
The most sensitive hearing childhood. At birth, a person can hear from 20 to 20,000 hertz, with age the upper threshold decreases to 15,000 hertz.

Organ 3: Nose

The nose is an important element of the human body, as it is responsible for two main functions at once - smell and breath.

Description of the building

The nose has several components:

1. External nose - consists of cartilage, bones and skin covering them.

The skin of the nose contains a large amount sebaceous glands. The muscles of the external nose usually do not function, but connect it to the entrance to the nasal cavity.

2. The nasal cavity is located between the orbits, the oral cavity and the anterior cranial fossa. Through the nostrils, the nasal cavity communicates with the external environment. The nasal cavity includes:

The walls of the nasal cavity are lined with small cilia that prevent small debris and dust from entering the nasal passage.
The olfactory center is located in the upper part of the nasal cavity.
The inferior nasal passage is located between the floor of the nasal cavity and the turbinate. It contains the nasolacrimal duct.
The middle nasal passage is located between the middle and lower nasal concha.
The upper nasal passages contain smell receptors (about 10 million)
The nasal passages that communicate with the paranasal sinuses.

3. The paranasal sinuses contain air cavities. There are four pairs of paranasal sinuses:

Maxillary - the largest, located in the body of the upper jaw. The promotion of mucus through the sinuses goes up to its medial angle, where the fistula with the middle nasal passage of the nose is located. The air pressure in the sinus is the same as in the nasal cavity. Maxillary sinuses divided into many partitions, if any is inflamed - this will show the x-ray.
The sinuses of the ethmoid bone are individual cells separated by bone plates. There are anterior, middle cells that open into the middle nasal passage and rear ones that go into the upper one. Near the sinuses of the ethmoid bone passes the optic nerve.
Frontal - have several walls, the dimensions of which are often individual.
The sphenoid sinuses are located so that the outflow of fluid from it and mucus occurs into the nasopharynx. Each sinus has four walls of different sizes.

Functions

The main functions of the nose:

Interesting Facts:

The nose grows throughout life, as do the ears.
With a sneeze reflex, a person is born and his style is similar to his parent.
There are about 14 nose shapes, the most common of which is the fleshy nose.
One of the signs of aging is the drooping of the tip of the nose due to the breakdown of collagen and the constant action of gravity.
The most favorite smells of a person are fresh pastries, coffee and freshly cut grass. Often stores smell of coffee and fresh pastries, as this smell increases a person's desire to buy.
It is known that memory is sharpened with the experience of strong emotions. Smells are closely related to the events that trigger these emotions.
People have approximately 12 million olfactory receptors, but their number decreases with age, and older people are less able to distinguish smells.

Organ 4: Language

It is hard to imagine life without taste buds that distinguish food, because there is so much goodness around.

Description of the building

The tongue can be divided into three parts - body, root and apex. The entire tongue is covered with epithelium and papillae:

The salivary glands are located at the top of the tongue and along its edges.

The sense of taste is able to conduct nerves:

Glossopharyngeal nerve.
Drum string of the facial nerve.
Nervus vagus.

The taste bud has an oval shape and consists of cells:

Taste sensory epitheliocytes - contain receptor proteins (bitter, sweet and acid sensitive) that are in contact with microvilli.
Support cells - support taste sensory cells.
Basal epitheliocytes - provide the restoration of the first two types of cells.

Solutes enter taste pits through taste pores. They are adsorbed on microvilli and act on receptor proteins. The sensory cell is excited, which pick up the nerve endings and carry information to the brain cells about the taste.

Functions

Sensitive - contributes to the perception of taste, pain and heat.
Protective - renders the mucous membrane of the tongue impermeable to viruses and bacteria.
Suction - provides the introduction of drugs, for rapid absorption, through the mouth.
Plastic - allows the epithelium to quickly renew itself in case of tissue damage.

Interesting Facts

The tongue contains fungiform papillae, each containing 50 to 100 taste buds.
15 - 25 percent of people on Earth have a "super taste". Such people have more taste buds on their papillae than others. The number of papillae in such people is also increased.
The taste of food is determined not only with the help of the tongue, but also with the nose.
There is a magical fruit growing in West Africa that will make sour foods like lemon taste sweet when eaten.
During an airplane flight, the sensitivity to salty and sweet foods is reduced due to the high noise level, but the food seems to be more crispy.
Taste buds live for about 7 to 10 days, after which they are replaced by new ones, so the taste you felt today may be different from the one you had two weeks ago.
Spicy spices added to dishes do not stimulate taste buds, but pain buds that connect to nerves.
The human tongue is able to sense sugar in water in a ratio of 1:200.

Organ 5: Skin

Touch is one of the five types of human senses, the ability to distinguish objects and their temperature with the help of touch.

Description of the building

The skin is made up of three main layers:

Skin appendages are hair, nails and skin glands. Thanks to a large number nerve endings of the skin, a person is able to touch with the help of tactile touches. When touching, the motor analyzer also plays a role.

Skin receptors that are part of nerve fibers epidermis and dermis provide a connection between a person and the external environment.

Functions

Receptor (touch) - thanks to the nerve endings.
Thermoregulatory - heat radiation and sweating.
Protective - protects the body from the ingress of chemical and mechanical substances, radiation and microbes.
Removes metabolic products and salts with sweat.
Participates in water-salt metabolism.
Promotes the absorption of oxygen and the release of carbon dioxide.
Through touch, it helps a person to distinguish objects, their temperature and shape.

Interesting Facts

The first sense that a newborn baby has is touch.
If people blind from birth begin to see, they will not be able to immediately identify objects that they previously touched by one glance, without touch.
The receptors responsible for touch are found not only in the skin, but also in the muscles, mucous membranes and some joints.
If children with mental disorders are rubbed on their backs, their perception environment improve.
If you touch the hands of a person a little, his arterial pressure slightly decrease and heartbeat will decrease.
The weight of the skin is about 15 percent of the total human mass.
If a premature baby is stroked daily, gently touched, he will gain weight 55 percent faster than babies who are not touched.
About 600 ml of water is excreted daily with the skin.
The thinnest skin is 0.5 mm on the eyelids and eardrum, and the thickest is 0.5 cm on the soles of the feet.

If you eat too much, your hearing becomes less acute. So you can do yourself a disservice by having a big meal before going to a concert or theater. Try limiting your food intake a bit if you need perfect hearing.

Approximately a third of the world's population can see perfectly no further than 6 meters. People who wear glasses or contact lenses, obviously do not suffer from loneliness - two-thirds of humanity cannot boast of perfect vision. The percentage of people with visual impairment only increases with age.

If saliva can't dissolve something, you won't know what it tastes like. So that food or something else has a taste, chemical elements it must be dissolved in saliva. Don't believe? Try wiping your tongue before tasting food!

Women are better at smelling than men. Studies have shown that women are much more accurate in identifying odors. They better recognize the smells of citrus, vanilla, cinnamon and coffee. By the way, 2% of humanity is not able to smell at all.

The human nose can remember 50,000 smells, while the nose of a Bloodhound dog is millions of times more sensitive. However, this does not mean that your sense of smell is useless. A person can recognize a huge number of smells and remember many of them.

Even minor noises can cause pupil dilation. It is believed that this is why surgeons, watchmakers and representatives of other professions, whose activities are associated with delicate manual work, do not like extraneous noise. Sounds can provoke a change in the focus of the pupils and distort what a person sees - and this is much more difficult to work with.

Every person gives off a unique smell, except for identical twins. Newborns can recognize the smell of their mother, many of us recognize the smell of loved ones. Part of the smell is genetically predetermined, but, in addition, the environment, food and personal care products - this is a list of those factors that affect the smell of the human body.

Human body- this is one of the most amazing mechanisms created by nature. That is why it has been the subject of study for several hundred decades. Learning a language, compared to learning other organs and muscles in our body, can be especially entertaining. We all know that the tongue is used for eating food, producing speech, spitting and swallowing saliva. In addition to all this, we can use the tongue when kissing. Doesn't language seem like a much more interesting organ given all this information? So, want to learn more about this amazing sense organ? If yes, keep reading.

Our tongue can recognize sweet, sour, salty, bitter tastes and umami (protein taste or “fifth taste”). Just imagine how amazing it is. In fact, the tongue is the only taste-recognizing muscle in our body, since there are approximately 10,000 taste buds on the tongue (2,000 of these taste buds are located under the tongue, on the inner surface of the cheeks, on the lips and palate). We can taste salty and sweet tastes with the tip of the tongue, bitter tastes with the base of the tongue, and sour tastes with the sides of the tongue.

The human tongue is considered to be the strongest muscle in the body and also the most sensitive.

Moreover, it is also the most flexible muscle. Among other things, our tongue acts as a natural tool for brushing teeth, and wounds on it heal much faster than on any other part of the body. The color of a person's tongue indicates whether he has any diseases that should be addressed. Normally, at good health our tongue should be pink. If the language gets White color, this usually indicates the development of a fungal infection. On the other hand, a change in the color of the tongue to yellowish indicates the presence of either a fever or stomach problems.

Our tongue is responsible for registering taste signals and transmitting them to the brain. Each taste bud that sends information to the brain contains approximately 10-15 receptors. Since the language is characterized by the presence of various nerve cells, signals are sent to the brain in such a way that the latter can register and differentiate a variety of aromas and tastes.

If you happen to look at your tongue through a magnifying glass, you may notice that it has tiny bumps all over its surface. In fact, there are thousands of these tiny bumps on the tongue. Inside these bumps are taste buds, which register different tastes. Our tongue must be wet - it needs saliva to determine the taste of food. Simply put, a dry tongue will be unable to communicate what it tastes like. It cannot differentiate between 5 different flavors.

So, if you put a slice of lime on a dry tongue, your brain will not understand what it tastes like.

The human tongue is in some ways similar to fingertips. Let me explain in what way. Each person's tongue has a unique shape and a different number of taste buds. That's why tongue prints are different for everyone, just like fingerprints.

Of all the muscles in the body, the tongue is the only muscle attached to only one side. Every other muscle in the body is actually fixed on both sides. The texture of the tongue is usually rough. If you haven't noticed it, check it out now. Although 85% of people can roll their tongue, not everyone can do it - only some people are able to fold their tongue, and this is a fact.

These were amazing facts about human language for children and adults. We are sure that you had mixed feelings when you heard about some of them. Keeping abreast of events and raising the level of knowledge about our body and its functions is increasingly becoming a necessity today. So if you find this article entertaining, check out the article about amazing facts about human body for more information.

The sense organs are "tools" that allow a person to interact with the outside world: to see, hear, feel aromas, tastes and touch. The information coming through them is sent to the brain in order to get a complete picture of the events taking place and respond with a certain reaction.

Many amazing facts are known about the sense organs, but they still remain a unique, not fully explored world, in which there is still room for new discoveries and observations.

Eyes and vision

Vision gives people about 80% of information about the world around them. Blind people develop better other senses, but most perceive information with their eyes in order to navigate in space and be aware of ongoing events. In addition, there are people who are colorblind, with a congenital or acquired inability to distinguish one or more colors. Recorded by statistics amazing fact: Among the world's population, 8% of men and only 0.4% of women are color blind.

It is also known about vision that:

A person cannot sneeze without closing their eyes. This is a protective measure of the body, which avoids rupture of the eye capillaries.
The eyes of most children are gray-blue at birth, but only by the age of 2 do they acquire their permanent shade.
About 1% of people with different colors of the iris live on the planet, and only 2% of people with green eyes.
The blue-eyed people of the entire planet have one common ancestor who lived about 7000-10000 years in the territory of modern Spain. After analyzing the remains found, scientists found that they belong to a man who is the oldest blue-eyed person known to scientists, while the rest of the people of that time were brown-eyed. This unique feature is due to a mutation in the HERC2 gene, which also determines the blue color of the eyes in modern humans.
An adult blinks every 8 seconds, closing his eyes for 1-3 seconds.
Lacrimal glands are able to secrete tears only after the 2nd month of life.
The eyes cannot freeze because they lack nerve endings.
The cornea is the only place in human body that does not receive oxygen.
Eyes cannot be transplanted, because in case of separation ophthalmic nerve from the brain, he will immediately die. But doctors have learned how to successfully transplant the cornea to people.
With loss of vision at a conscious age, people continue to dream with pictures, while those who are blind from birth do not have dreams with images.

Ears and hearing

The ears are "responsible" for the adequate perception of sound information, which allows you to warn against dangers, determine the source of a sound, or enjoy a beautiful song. The human ear is not only a sensory organ, but also an element of the vestibular apparatus. Near auricles channels are located, which are a kind of gyroscope: they help to keep balance and navigate in space.

In addition, other, no less amazing facts are known about the ears:

Putting a shell to your ear allows you to hear the sound not of the sea, but of your own blood circulating through the veins.

Complete or partial hearing loss can occur at any age. Most often this is due to prolonged exposure to loud sounds, otitis media, viral and infectious diseases.
After a heavy meal, hearing decreases slightly.
Ears, like the nose, are another part of the body that grows throughout life. But it is not the auditory ossicles that grow, but the size of the earlobe changes.
Hearing problems are more common in men than in women, because the stronger sex is more likely to go to work in places with increased level noise pollution.
Favorable volume of sounds for people - up to 50 decibels (noise level during a normal conversation). Sounds exceeding this indicator are related to noise load and adversely affect metabolic processes in the body and work. immune system in particular, which can manifest itself in a reduction in the production of vital antibodies, a weakening of immunity to infectious diseases and tumor processes.

Nose and sense of smell

The nose is the most prominent part of the face and is one of the defining factors of beauty. Not surprisingly, dissatisfaction with its shape or size often forces people to resort to rhinoplasty - changing the shape of the nose. This procedure is the second most popular in plastic surgery after breast augmentation.

In addition, the nose plays an important role in the recognition of smells and tastes. To be sure of this, it is enough to try favorite dish with a tightly pinched nose: it will surely seem more insipid or generally tasteless.

For some people, a well-developed sense of smell provides a comfortable existence, so it becomes necessary to insure oneself against its sudden loss. For example, perfume experts sometimes insure their nose, and food experts use additional insurance in case of loss of taste sensitivity.

The following amazing facts about this sense organ will tell you that the nose not only performs a number of vital functions, but also has a number of unusual features:

The shape of a person's nose is formed only by the age of 10, and it continues to grow throughout life.
In a calm state, a person breathes “at a speed” of 2.4 km / h, and during a sneeze, the speed of air ejection from the nasal passage reaches 160 km / h. The style of sneezing idiosyncrasy each person, but it can sometimes coincide with family members.
A person distinguishes up to 10,000 different odors, while it is believed that women recognize odors better than men.
In 2% of the world's population, the sense of smell is completely absent. This disorder is called anosmia.
Dropping of the tip of the nose (gravitational ptosis) is one of the signs of aging. The process is due to the weakening of the ligaments that hold the nasal cartilage, and a decrease in skin elasticity due to the breakdown of collagen and elastin in it.
Among the favorite smells, people usually name the aroma of freshly cut grass, pastries and coffee. The last two are often used in stores as these scents encourage shopping.
There are about 12 million olfactory receptors in the nose. With age, their number decreases, so older people distinguish less aromas. At the same time, the expression “smell like a dog” in relation to a person will not be entirely fair. In these animals, the number of receptors responsible for smell reaches 14 billion.
The sense of smell is sometimes called the organ of memory, since smells can remind a person of even the most distant events.
The human nose cannot smell certain life-threatening substances, such as natural gas. In order to be able to hear the leak, special compounds are added to the gas, providing it with a characteristic smell.
Most people pick their noses with their index fingers, but this one bad habit There is a scientific name - rhinotillexomania.

Language and tastes

The main organ responsible for the sense of taste is the tongue. This is an important element of the digestive system, which takes part in the process of chewing food, mixing it and moving it into the throat. The tongue is covered with special papillae that transmit information in the form of nerve impulses to the brain to identify sour, sweet, salty or spicy foods. To determine them, the lingual surface must necessarily be wet, that is, moistened with saliva. If you put the product on a dry tongue, the brain will not receive any signal about its taste.

Language is also an indispensable part of the speech apparatus, without which a person simply cannot speak normally. In addition, it is the most flexible and mobile muscle in the human body. It is fixed on one side only and can take a variety of different forms, but only some people are able to roll the tongue in the form of a "tube". At the same time, this ability is observed much less frequently in men than in women.

Here are some more amazing facts about the tongue as one of the main organs responsible for the sense of taste:

If you eat a few fruits of the Magic Fruit (a plant native to West Africa), for the next few hours, all sour foods will be perceived as sweet, and sweet ones will be completely tasteless.
Spicy foods do not irritate the taste buds, but the pain buds that are connected to the nerves.
The human tongue will sense sugar dissolved in water if the proportion is 1 to 200.
The owner of the longest tongue in the world among women is Chanel Tapper (9.75 cm), among men - Stephen Taylor (9.8 cm).
Taste buds on the tongue are updated every 7-10 days, so foods with the same tastes can cause different sensations if you try them 2 weeks apart.

Skin and touch

If a person's vision deteriorates, he turns to an ophthalmologist, hearing is impaired - to an otolaryngologist. But who to turn to when the ability to perceive the world correctly is impaired? A therapist, dermatologist, neurologist or neurosurgeon can help with this problem. The nature of the disorders may vary, but there is no doctor who specializes exclusively in touch. For a long time, scientists paid little attention to this feeling and the skin responsible for it - the largest organ of the human body. Its average area is about 1.5-2 m², and the average weight is 4 kg. During life, it is impossible to accurately weigh it, but the approximate mass can be calculated using the formula: divide its own weight by 16.

The thickness of the skin differs in different parts of the body: the thinnest layer is on the eyelids and eardrum (0.5 mm), and the thickest is on the soles of the feet (0.5 cm). Skin covering covered with a unique pattern of lines, triangles and rhombuses, forming a kind of grid. It is best seen on the soles and palms. The purpose of microgrooves in the form of fingerprints is still a mystery. Some scientists believe that they reduce the sensitivity of the fingers so that the brain can concentrate on more important tasks. Others, on the contrary, believe that the embossed skin on the fingers makes it possible to enhance the tactile perception of the surface being examined.

There are many more amazing facts about this largest sense organ:

Skin color is directly proportional to the amount of melanin produced. People who do not have it at all are called albinos, which occurs in 1 in 110,000 cases.
The skin of an adult is completely renewed within a month, and in newborns this process takes 72 hours.
Burning from pepper or chill from mint is not an influence of tastes, but of touch. These foods irritate the receptors responsible for the sensation of temperature.
It is believed that women feel better with their hands than men. But this is due not so much to the floor, but to the size of the hand. The number of nerve endings is approximately the same for everyone, but with a small hand size they are located more densely, which increases sensitivity.
Round wounds take much longer to heal compared to other wounds. This amazing fact was noticed by the ancient Greeks and they often changed the shape of wounds for their faster healing.
According to scientists, when a person's face turns red from embarrassment or physical activity, the stomach lining also turns red at the same time.

The role of each of the sense organs is important not only individually, but also in interaction with the others. Only their joint work allows you to fully enjoy the picture of the world and all its shades.

The muscular organ in our mouth performs a considerable number of different functions for the body, therefore interesting facts about language a person will always be relevant to reading.

Babies suck their mother's milk with their tongue. In some babies, this organ is slightly larger than standard sizes. However, it does not prevent them from simultaneously performing sucking and swallowing actions. At the same time, children have time to inhale the air.
Human language has the ability to distinguish 4 different taste: bitter, sweet, sour and salty. On its surface are special papillae, the sensitivity of which helps people enjoy food. These taste receptors are located in the soft palate and in some places in the pharynx.
The total number of taste buds affects the feeling of hunger. The fact is that people who have a small number of such receptors are forced to eat more often, since they do not feel the characteristics of food and drinks. This condition causes obesity.
The organ of taste plays an important role in digestion.. Everything we eat dissolves in our mouths. The glands of the papillae are activated, which produce the right amount of saliva for different foods. Also, the tongue is involved in mixing food and pushes it down the throat.
The color of the tongue indicates a person's health. In the normal state, the organ has a pale pink color. white plaque indicates the presence of a disease. The yellowish color of the taste organ occurs in people suffering from problems of the gastrointestinal tract.
On the surface of the tongue lives a huge amount anaerobic bacteria . They cause bad breath. One of the most effective tools for dealing with them is a toothbrush, which is used daily during cleaning of the tongue.
Tongue can heal faster than others. The tongue is better than other organs supplied with blood vessels. A small wound or sore as a result of biting appears there very often. At necessary care and processing everything heals in about 1-2 weeks.
Some people develop a taste disorder called dysgeusia. It appears with diabetes, anemia, dysfunction of the endocrine glands, etc. People with this disease feel metallic taste and burning sensation in the mouth. They like to try unusual substances: clay, lime, chalk.
Women are 20% better than men at distinguishing sweet tastes. Ladies are also 10% more sensitive to acidic foods. This fact is explained by the physiology of the body. They have more taste buds, so the majority of the female population of the Earth loves candies, cakes and other sweets.
Smoking affects the taste buds. On the tongue of a person who abuses cigarettes, a yellow-gray coating gradually forms. It has a dense structure that is difficult to remove.
The tongue is the most mobile and flexible muscle in the human body.. It is able to take different forms and is fixed only on one side. At rest, this part of the body completely fills the oral cavity. However, his muscles are not the strongest in the body.
Some people can roll their tongue into a tube. Scientists believe that this ability is due to genetics or environmental influences. However, it is not at all necessary that the abilities of the parents pass on to the children. Scientists are still working on an explanation for this phenomenon.
Each person's tongue print is unique.. This is due to the fact that all people have differences in its structure. Each of us has its own arrangement of taste buds, furrows and other elements of this organ. It is believed that in the near future there will be a special tool for imprinting the tongue.
Fans of tongue piercing do not understand what consequences await them. Mostly teenagers like to do this, who then suffer from illnesses. oral cavity, which is caused by constant injury to the gums.
14
First tongue transplant done in 21st century. The reason for the intervention of doctors was malignant tumor, which did not allow the body to function normally. The operation lasted 14 hours and was successful as a result.
