Obviously, one of the basic five senses of the human being is the sense of touch.

Among the various waves of different frequencies which come to the brain continuously, there are the signals that are related to the sense of touch.

As a matter of fact, these stimuli are present in every moment of our daily lives and they can be perceived through the skin. The skin is the basic element of the anatomic structure. The sense of touch is one of the most developed tools of the means of perception, its sensitivity varies according to the various parts of the body. The nerves pertaining to sense are not distributed evenly over the surface of the body, therefore some parts of the body are very sensitive and some other parts are not as sensitive.

The tips of the fingers, especially the inside parts are very sensitive in terms of feelings. They are being supported by the nails from above, this increases the sensitivity more. As a matter of fact if there were no nails, then the process of holding would be impossible . Apart from these, the inside parts of the hands, the face, the sexual organs and the area surrounding them are sensitive parts of the skin. In parts where there is increased fatty tissue such as the hips, the back and the belly there isn’t much sensitivity.

The senses such as itching and tickling do not have special nerve endings specially for them.

When the bioelectrical activities enveloping the whole body become interrupted then, the result is the itching. The tips of the fingers and other parts of the body repair this defect by rubbing. The skin performs a great portion of the activities that the organism has with the outer realm. In animals which have a lower rank in the evolutionary phase such as the earthworm and the snail, the skin also performs the functions of respiration and the excretion of the metabolic wastes.

In mammals there are special organs and systems which perform these functions, therefore in the human being the function of the skin is limited with forming an effective barrier for different substances, regulating the loss of heat and transferring the stimuli.

We know that the living cells can go on living only in liquid. On the other hand, the static electricity arising from the working of the whole organism is being discharged through the skin especially through the keratinised attachments of the skin (eg. the hands, the nails etc.) The skin forms a barrier between the air and the parts that have contact with it. This layer acts as a protective cloth for the living organisms in the lower layers.

The pain that reaches the brain can be beacuse of a physiological impact, or astrological influences or due to the stress of the daily life. Every brain does not live the function of pain which is formed by the touch and the magnetic area to the same degreet. In people who have considerably high stress levels, the pain is directed to another organ of the body so that the brain will not get damaged. Then, that area overtakes the pain.

In structures that have limited activities among the cells of the brain, the ratio of feeling the pain is greater than those who are more active.

The total area of the skin is 1.5 square meters, it is 0.5- 2mm thick and its colour varies according to different races. In areas close to the equator, the people have a dark skin and they are called ‘’black’’, because the rays of the sun cause a mutation in the structure of their DNA’s (deoxyribo nucleic acid).

The human being wants to form a relation with the ones that he can perceive by the eye through the senses of hearing and touching.

The personal electrifications become concrete in the cortex of the brain in the region of imagination through the sense of touch.
