Introduction

People were always curious about feelings and senses from the earliest times; If there is any idea about the feeling of something that comes to their mind, it is not possible to understand the senses by the known senses. People have come to know that we have five senses (eyes, ears, nose, tongue, skin / touch) to get different feelings, and from here the concept of sixth sense of human being has emerged. In other words, when we feel that beyond these five senses we find that the feeling is available, then people have blamed the sixth sense.

Again many people say that the sixth sense means the indulgence gained through the mind and the sixth sense which is felt directly through the mind without the help of a current customer (receptor)! The notion of such feelings is significant - see / guess the future, communicate with the phonics (as shown in the 1999 Hollywood movie "The Sixth Sense" ), not being present at the scene, feeling it at the time of happening, etc. The meaning of the sixth sense is, in general, what it does not actually exist, it will not be ascertained; The essence of the writing is: Are we really only five senses? Or is it just a misconception? And yes, if the idea of ​​the five senses is wrong, then in the sense that the word "sixth sense" is used in the conventional sense, it should not be used anymore; Instead it would be better to use different words.

Our known senses

Usually sense means "a system that is composed of sensory cells, cells that respond to a particular physical phenomenon and the central nervous system is related to certain regions ( Where the signals are accepted and translated) ". Now come true words. "People only have five senses" - It's wrong! People have more sense than five and most researchers think that the number is twenty or more! Generally, we know the five senses that are:

1. Opthalmoceptor
2. Audioceptor
3. Gustaoceptor
4. Olfacoceptor
5. Tactioceptor

And the limitations of our thoughts about those senses we are not aware of, and many of our thoughts about the meaning of this three-episode episode. But in the endeavor to make the text complete, it is also briefly presented to all the known senses. The researchers who are already aware of the human senses are trying to give a brief introduction of significant senses -

1. Visions(Opthalmoceptor):

The retina of the eye (retina) customer two different types of cells responsible for vision, namely a cell and rod cells. No cell is responsible for the color feeling in our eyes, but it is not suitable for gentle light that is less sensitive to brightness. On the other hand, the rad cells are very sensitive to brightness, but are unable to provide color feeling in gentle light. These cells are connected with optic nerve and transmit information to the central nervous system through which they get the feeling of vision through processing.

2. Hearing (Audioceptor):

to be medium (such as air or water), vibration detection and translation of the hearing in the brain. When a vibration comes in contact with the ear drum, it also vibrates there and it is transmitted and translated into the central nervous system through an adjacent nerve through a narrow nucleus called the cochlea located in the inner ear. . However, a particular species of animals can detect, feel, and translate a specific range of the frequency of the words. For humans it is 20 to 20000 hertz.

3. Tastes(Gustaoceptor) :

We basically get five different flavors; Such as sweet, salty, sour, bitter, and umami (the taste of amino acids glutamate that is present in meat and savory food). The remaining flavors are felt in combination with these flavors. There is a debate on that the taste is made up of five senses, because these five types of taste are obtained through the different taste of the tongue (taste bud) of the tongue. But it is generally considered to be a sense. The signal transmitted to the central nervous system through the adjacent nerve fiber to this sensation, originally originated from the chemical reaction of the food khoya on the taste-korakar customer.

4. Olfactory (Olfacoceptor):

It gives us a sense of smell. Under the nostrils of the nostrils, some specialized sensory cells play a major role in this process. When a molecule of some of these cells is connected to a specific customer, the central nervous system gets a signal and the smell of it increases. These molecules are basically of three types; Such as volatile small molecule odorants, non-volatile proteins, and non-volatile hydrocarbons.

5. Touching (Tactioceptor):

touch our skin, composed of the different types of customer. It responds to the mechanical pressure and distortion on our skin. Our skin mainly consists of four types of customers engaged in this work, such as Lamellar corpuscles, Tactile corpuscles, Tactile discs, and Ruffini corpuscle. These customers send signals to the central nervous system through the peripheral nerve fibers which generate the feeling of touch between us.

6. Concentration(Baroceptor) :

Capillary stays in any vertebrate artery. The concentration is usually sensitive to blood pressure and blood pressure information always plays a major role in maintaining normal blood pressure by transmitting to the central nervous system. They mainly show sensitivity to the contraction / expansion of arteries, as well as changes in blood pressure.

7. Thermal (Thermoceptor):

The heat is capable of sending signals of absolute and relative change in the temperature (innocuous) range. The interesting thing is that hot and cold feeling is done by a different type of customer. In the case of mammals, it is believed that for the feeling of warmth, their endoscopic sensory system is responsible for the myelin coiled C-fibers, and this work is done to provide a feeling of coolness, endangered sensory system A delta fiber with myiolin vein-free C-fiber and thin mesolin coated. (thinly my elinated A delta fibers).The heat is considered to be equivalent to multiple senses; However, it is not just because there is a different type of customer available for the warm and cold feeling, temperature changes have different types of customers based on identification strategies. The main thing to do is to monitor your body.

8. Tropical ( Pruriceptor):

Although weird to hear it is true that there is a whole different sense of itching! It is also the C-fiber work of the skin's endemic nervous system, but these C-tissues are structurally different from the C-Tissues of the body, although it is strategically different. Only 5% of our body's total C-Fibers occupy this kind of fiber. Typically it is felt due to various types of mechanical, thermal, and chemical stimulation in these fibers. The fibers reach these stimuli at the central nervous system and from there the origin of the scratching reflex response is derived. When we excite the excitement of the skin of the same area of ​​the skin and cheeks, which disturb the feeling of itching of the place, So during the hair stream our itch is mushy. However, it is only temporarily released from the itching during the hairstyle. The main function of the steroid is to give us warning through the presence of harmful chemicals on our skin or tissue so that we can take appropriate measures in due course.

9. Nociceptor :

At one time, experts felt that pain was felt due to excessive feeling of touch, but afterwards, paints have been found to have its own distinct sensory mechanisms. Pediatric patients of mammals are essentially some sensory neurons which can take various external / internal harmful stimuli, and they are located in almost all areas of the body. There are three types of customer presence in our body to provide a feeling of pain on the basis of location; Such as skin, cutaneous, somatic, and interpersonal (visceral). They are located in skin, bone, and inner organ, respectively.

10. Atmendriya (Proprioceptor):

This is very interesting sense. We can understand the relative position of different parts of the body through this sensation. For example, through this sensation, you can touch your nose / elbows with fingers, or scrub in the back of your back.

This sensation helps to understand the relative position of different parts of the body through the combination of completely different feelings with the help of different clients, so it is also considered to be multiple senses alone. In essence, three types of customers are engaged in this co-ordination. For example, muscle spindle in muscle, golgi tendon organ located in the tendon, and fibrous capsule in the trunk. The muscular tissue relates to the change in muscle length, and the golagic condoms and tissues of the muscles transmit the information about the muscles of the muscles and changes in the angle of the osteoarthritis, which are processed there. Again, this muscular mechanism works as a stress customer in the muscles of the lungs, stomach or intestine.
