A Perfect Perceiver: Skin
You can hold and carry objects with smooth surfaces like a glass, for example. You can feel softness when you touch a feather and hardness when you hold a stone. Perceiving all this and sending necessary signals to your brain, your skin has the characteristics that enable you to visualize the objects in your brain.
A great number of nerves exist in the fingertips. This provides you with facility in movement and does not cause any inconvenience. On the other hand, in "less important" regions, on a man's back for example, there are fewer nerve endings present. This is a very important advantage. Now, let's assume the opposite: Let's assume that our fingertips are quite insensitive while nerves are arranged in greater numbers at the back of our bodies. This, undoubtedly, would be very troublesome. In such a situation while we could not use our hands properly, we would feel the slightest object touching our back, the folding of our clothing, for example.
Human skin is a complex organ consisting of many layers, containing nerves for perception, circulation canals, airing systems and heat and moisture regulators which protect the body like a shield against the rays of the sun. Because of this, a man can be in great danger if a part of his skin is damaged. Under the skin is a layer consisting of fat. This layer of fat serves as insulation against heat. Over this layer is another one, most of which consists of proteins that give the skin elasticity.
If we were to lift the skin and look just one centimeter below it, the sight greeting us would be an unaesthetic, even frightful sight, where fats and proteins and various blood vessels exist. By means of the feature that enables it to cover these structures, the skin both provides a very important aesthetic contribution and also enables us to protect ourselves from outside factors. It will be sufficient to remark upon a couple of the functions of the skin that makes it vital for us and to ponder on them in order to understand the importance of its existence.
Human skin prevents the disturbance of the water balance of the body, is strong and elastic, can repair itself, protect the body from harmful rays, maintains contact with the outside world, and protect the temperature of the body in cold or hot weather.
Human skin, which functions as a sensitive
detector and an advanced air-conditioner meeting all kinds
of needs, is a blessing that has been created by God, with
the beauty it provides visually and the features it has to
protect man. The skin, about which many pages of books have
been written, once again displays God's magnificence in creation
