Speaking in scientific language, the human sense organs are the components of the anatomical and physiological system, which, thanks to multiple receptors, make it possible to obtain and analyze information from the internal and environmental environment.

Definitely, to underestimate what nature has bestowed upon man is the greatest folly. But what is known about the system of sense organs, and what facts still remain a mystery to its owners?

How many sense organs does a person have?

People learn about how many organs of sense they have in a person. Usually, already in preschool, children playfully, cheerfully and defiantly acquaint themselves with the senses. Crumbs, you can ask that the little animals on top, and a person below the eye? And he will, though after deliberation, answer that these are ears!

Ever since Aristotle, 5 sense organs in humans have been isolated, which transmit information flows to the brain.

This is about:

  • how many sense organs does a person have?organ of hearing;
  • body of taste;
  • organs of smell;
  • organs of vision;
  • organs of touch.

They are also divided into two categories:

  1. Distant organs.
    They provide the nose, eyes, ears, and here we are talking about perception. That is, in order for the brain to obtain reliable data, it is enough for a person to contact with objects, being at some distance from them.
  2. Tactile organs.
    This category includes the remaining main sense organs, which provide taste and tactile sensations. In this case, one cannot do without direct contact with objects, otherwise the analytical chain will be interrupted and the information will not reach the brain receptors.

It is important for a person that the entire system of sense organs works smoothly and without interruptions, and even minor violations can deteriorate the quality of his life.

A little about the mirror of the soul - the eyes

Even Heraclitus of Ephesus designated this sense organ as "a more accurate witness of what is happening than the ears." What eyes deserve such a high rank among other organs? In fact, their functions allow a person to receive the largest amount of data about the world. As for the structure of the eye, it is very complex, and the visual organ consists of many parts.

The outer part of the eye consists of:

  • human sense organs, eyessclera- connective tissue sheath; protects and supports the eyeball;
  • pupil- holes, giving the opportunity to see;
  • front camera- this area in front of the pupil, filled with moisture is a protective barrier;
  • iris- the thinnest diaphragm surrounding the pupil, the pigmentation of which is the color of the eyes;
  • cornea- her job is to refract light rays;
  • conjunctiva- the mucous membrane of the eye tissue of the eyes and eyelids emitting tear fluid; they are supposed to protect and moisturize the visual organ;
  • century- skin folds involved in the distribution of tears on the surface of the eye and are a protective mechanism;
  • eye sockets- bones, which is the receptacle for the eyeball, here are the vessels, muscle tissue and nerve endings.

Interior:

  • vitreous body- hyaluronic acid and water, refracting light;
  • lens- A natural lens that is responsible for focusing the vision;
  • retina- multi-layered shell, thanks to which people see in daylight, dim light and distinguish silhouettes in the dark.

In addition, the organ of vision includes several special devices:

  • lacrimal, including glands, tubules, nasal ductus and sac.
  • muscular - it's hard to imagine how many muscles are involved in the work of the eyes - straight, oblique, circular, as well as ensuring the rise of the eyelid.

All the human senses and their functions are aimed at a better perception of the surrounding world, and the eyes are capable of much. They allow a person to distinguish colors and feel the light, to have peripheral, central and stereoscopic vision. All images visible by the eyes are sent to the brain - the main center that controls absolutely all the processes occurring in the body.

Two ears - to better listen ...

Another important organ whose influence on a person’s life cannot be underestimated. It is not for nothing that in folklore and sayings of famous people there are very often phrases and aphorisms about ears and hearing: “Women love with their ears”, “You can hear harmony in silence”, “You need to keep your ears open”, etc.

human senses, earsCertainly, the organ of hearing deserves special attention, and if you disassemble its structure, you can understand that this is an amazing part of the body - a complex and at the same time functional:

  1. Central - includes nerve fibers ending in the temporal lobe of the cerebral cortex.
  2. Peripheral area:
    1. outer ear, consisting of the auricle, ear canal, eardrum;
    2. middle ear - including the tympanic cavity, Eustachian tube, mastoid process; these are two air cavities connected by a nasopharynx.
  3. The inner ear is a bone formation consisting of the vestibule, the semicircular canals, the cochlea and the vestibular analyzer.
The ears are able to perceive sounds, sound vibrations, conduct them and the waves to the receptors. Sounds can affect the emotional state of a person, and a lot has been said about the positive properties of music that a person hears.

Even Aristotle said that "when a person perceives the rhythm and melody with his ear, his mental mood changes." Of course, for this to happen, you need to listen to the “right” melodies that do not cause negatives.

Why is the nose considered the most curious organ?

Considering the human senses, it is impossible to ignore the nose, which allows you to breathe and smell the aromas. And as for curiosity, it is he who “is thrust into his own affairs,” “he was torn off by the curious Varvara,” and “turned up” when they are arrogant.What can we say, but in folk aphorisms there is always a wise grain.

The nose is a complex structure consisting of cartilage, bone and skin, and for its full operation it is important that all parts function. It consists of: root, apex, back, wings, septum and nostrils.

But this is the outer part of the organ, which is visible to the naked eye, and the structure of the nose also implies the presence of an internal cavity. It is located between the orbits, the oral cavity and the anterior cranial fossa.

facts about the human sensesThe composition of the nasal cavity includes the following sections:

  • walls with a ciliated surface - protection from dust and trash;
  • olfactory center - located in the upper region of the cavity;
  • nasal passages.
  • sinuses, located near the nose.

Such a structure of human sense organs is so thought out by nature that even the nose affects various systems of the body, besides the fact that it gives an opportunity to smell and breathe:

  • is an air filter;
  • moisturizes and warms these air masses;
  • protects against pathogens in the air;
  • forms pitch and timbral voice notes.

There are many studies on this body, and sometimes it turns out the most interesting moments, for example, the most pleasant smells that it can catch - the aroma of mowed grass, natural coffee and freshly baked buns.

Language - helps to know the taste of life

It is an organ with many receptors capable of distinguishing tastes. It consists of the root, the body and the top, and its entire surface is covered with epithelial tissue and a large number of papillae:

  • filamentous;
  • mushroom;
  • leaf-shaped;
  • gutter;
  • salivary.

But in order for a person to feel all the taste richness of a dish, it is necessary that the nerve endings take in and carry them to the brain. Such a task confronts the glossopharyngeal, wandering nerves and the tympanic string of the facial nerve.

The language allows people to communicate, protects the body from viral and bacterial pathogens, and in addition to taste, it allows you to feel pain and warmth. According to Hans Georg Gadamer, “Language is an environment that unites“ I ”and the rest of the world.”

Modern scholars study the effects on human senses of various external factors - music, gadgets, the Internet, and some consider a person hostage to their own feelings.
