How many senses do humans have: detailed analysis.
Content
The question arose, how many senses do a person have? It was also proved to Aristotle that a person has only 5 senses, but controversial options are constantly trying to add to them. In this article, we will examine in detail 5 senses in humans and in the hotel section we will talk about additional options offered by skeptics from around the world.
How many senses do humans have: name
In distant antiquity, when a person has not yet been operated on and, therefore, no one knew about the presence of the brain, the sages were noticed that a person has certain senses that are responsible for contacting the body with the outside world.
So, so as not to get confused in this matter, let's clarify:
- Feelings are vision, touch, hearing, etc.;
- The senses are parts of the body with which we can hear, see, etc.
How is the process? External stimuli fall on the receptors of the sensory organs, and the organs already transmit information into the brain through the nerve endings. And already the brain processes, analyzes and uses this information. Since a person has these skills from birth, he copes with them automatically.
Human senses have 5 and this and this:
- Eyes;
- Ears;
- Nose;
- Leather;
- Language.
If one of the organs fails or stops working, other organs begin to work more carefully, trying to fully understand the picture of the outside world. That is why the concept arose that if you deprive a person of one feeling, another is aggravated by another. A person does not become more ingenious, as they say in comics, on the contrary, he has been fighting all his life for every inch of information.
It is also worth noting that the senses are conditionally divided into two zones:
- Tactile - These are bodies that receive information using direct contact of the outside world and organ. This is leather and tongue;
- Distance - These are the organs that receive information at the distance and never contact with objects of the outside world. These are ears, eyes and nose.
As you can see, everything is simple. There can be a lot of feelings and, of course, it can be disputed for a long time, but the senses are only 5 and, despite many disputes, scientists have not yet discovered additional organs.
Human senses: eyes
We begin the analysis of the human senses from the "mirror of the soul", the most beautiful and bottomless. Yes, this is what the organ of the human senses is called the eye that is responsible for vision. They work from six independent muscles that are responsible for the movement of the lens in different directions, as well as concentration on a certain subject.
When the doctor reports that vision has become worse, in 80% of cases it is for excessive tension or muscle relaxation, as well as that the muscles of the eyes are weak. The retina and cornea are also responsible for vision. It is on it that the rays of light falls, refracted and give signals to the brain. But the nerve endings are excited under the influence of colors in different ways, and from their signals our brain perceives a full palette of colors.
There is a myth that men see fewer shades than women, but it is fundamentally wrong. It all depends on the skill acquired in life. Girls often consider fabrics, textures, shades, study the palettes of flowers in order to match other girls and understand in the changeable world of fashion. Moreover, if the boy is engaged in drawing or design, he understands shades no worse than girls. So the nerve endings of boys and girls have the same and nothing to do with it, the whole question is in male inattention.
Human senses: ears
Hearing is so much in this feeling. It is he who helps to recognize his favorite voices, capture a familiar melody and, of course, he warns us against dangers. And all this is due to the complex organ - the ears.
Our ears consist of three parts:
- Inner ear;
- Middle ear;
- The outer part of the ear.
It is noteworthy that this body is responsible at once for two feelings. The first feeling is, of course, a rumor, but the second sense of balance, balance, the location of the body, which is also considered a vestibular apparatus.
The structure of the ear is arranged in this way. The outer part of the ear (ear sink) is located so as to catch sounds to the maximum and at the same time carefully protect the rest of the ear from the external aggressive environment. The entire sink narrows to the recess and creates a auditory passage into the middle ear. The aisle is placed on the aisle, which secrete the sulfur substance that protects the auditory passage from the sorcerers, which are delayed on the substance and removed out.
It is worth noting that the auricle works like a huge antenna, attracting sound vibrations to itself, and passes them to the eardrum. Next, we go to the middle ear, which resembles a forge (hammer, an anvil and a stream). Thanks to these parts of the ear, the eardrum conveys the sounds of the “snail” that reads sound vibrations.
It is worth remembering that colds can inflame the ears, from which not only the hearing worsens, but also the operation of the vestibular apparatus is disturbed.
Human senses: nose
Breath is something without which a person cannot live. But the nose is responsible not only for the respiratory apparatus, but also for the sense of smell. Thanks to the receptors that are located in the inner parts of the nose, aromas inhaled with air are recognized and transmitted to the brain.
This is not only an aesthetic feeling, but also a feeling that is responsible for the safety of human life. When you feel pungent odors, the body can understand that the air is infected and a person needs to take quick actions. It is the smell of Gary that suggests that the fire is nearby, and the smell of chlorine suggests that its huge concentration in the air can be poisoned in pairs.
It is important to remember that when smoking, the sense of smell is dull, and it becomes more difficult for a person to recognize smells.
Also, during colds, the sensory organ is experiencing inflammation and this leads to a deterioration deterioration. But if the cold has passed for more than 7 days, and the sense of smell did not return, you need to consult a doctor.
Human senses: language
This sensory body is cunning and controls the nutrition of most people on the planet. It is in the language that the receptors responsible for the feeling of taste are located. At the same time, it is worth remembering that each person has receptors in a special way, and they feel different taste in different ways. In addition, the feeling of taste can change with malnutrition.
For example, a person who puts a lot of sugar in food, salt ceases to feel these seasonings over time and begins to put even more. Thus, we get a person who puts 5 tablespoons of sugar in a cup of tea and he seems to him not sweet enough. Others say that he is a great inventor, but he really does not feel sugar like a person who does not consume sugar or consumes in small quantities.
And, of course, we could not mention the notorious seasonings of artificial origin, which enhance the taste of the product, but subsequently when you start, there are food without these seasonings, the food seems fresh and not very tasty.
The language feels only four tastes (sweetness, sourness, bitterness and salty), but certain products create a certain combination of feelings, which is associated with this product later.
So, consider how our language works. If you take out the tongue and look in the mirror, you will see that it is not even and has many loose papillae. It is these papers that are responsible for the feeling of taste, but on each part of the tongue, the papilla is responsible for their taste:
- The tip of the tongue is sweet;
- The very back of the tongue is bitter;
- The upper plane of the tongue is salty;
- The side parts of the tongue are sour.
At the same time, it should be understood that all kinds of diseases that carry, incidentally, a colored plaque on the tongue (white, yellowish, etc.) affect the feeling of taste. The worsening of the sense of smell also entails a deterioration in a sense of taste.
Human senses: skin
For some time, an organ of feelings - hands, fingers tied to a feeling of touch. But as practice has shown, each part of our body can touch, we just, in order to feel a new object, most often we study it with our hands. The skin is the largest organ of feelings, as our whole body covers.
The sensation body works quite simple. When touching the skin, the nerve endings “read” the information and immediately transmit it to the brain, which already analyzes and works with the information received.
Human senses: controversial issues
At the beginning of the article, we promised to point out the controversial bodies of human senses, or rather the feelings that they want to attribute to this list, but at present scientists are categorically against. Opponents of this theory assure that there are really much more feelings, but the organs do not apply to these feelings. In addition, many of the voiced feelings are most likely thoughts and emotions, which does not apply to the senses at all.
- For example, a feeling of beautiful. This is most likely a person’s thoughts, and the skill acquired over the years, which recognizes certain artistic styles and solutions.
- The notorious propriocation (a feeling that gives an understanding where the parts of the body are located, even if you do not see them) and equibriocument (a feeling that gives balance) is a long time ago to the vestibular apparatus, and the organ responsible for these feelings is the ears, which already enters the aforementioned five.
- Thermocument (sensations of heat or cold with leather) or noocicentation (the feeling of pain with skin, joints and internal organs) also relate to tactile feelings and the skin organ is responsible for them (except for pain in the joints and internal organs that are carried into a separate category).
- Intuition - "sixth Sense". For a long time, critics want to introduce intuition and supplement the famous five. But the question is what. Intuition has no organ! Yes, we can have hundreds and hundreds, no one disputes this. But the senses are only 5 and we listed them above.
We hope our article helped to understand the issue of the senses, and now you will easily be the senses from other parts of the human body.
