THE SKIN – THE FUNCTIONS OF THE SKIN(GENERAL INROMATION)
If we touch a piece of material with our fingertips, trying to find out whether it is pure silk or linen, twenty-five tiny structures cooperate to help us test the fabric. We could catch a finger in the door and feel nothing at all if it were not for the 200 sensation structures per square centimetre of skin that communicate the injury to the brain via the sensory nerves. Scalding, burning and a Baunscheidt (stimulation) treatment can cause the formation of large blisters filled with fluid, with the top layer of skin becoming separated from the one beneath it.
The outermost layer is called epidermis and consists of cells. The deep inner layer, the corium or dermis, is much thicker and consists of fibrous tissue. The epidermis has more than twenty cell layers that contain no blood vessels, which is why the skin does not bleed when it is rubbed off, nor produces any sensation of pain. However, when the dermis, which lies under the epidermis, is touched or brought into contact with water, there is an immediate reaction. When engaged in physical work, handling earth, sand, lye and the like, soapy water rubs off several layers of the epidermis when the hands are subsequently washed. But on the following day there will already be the same number of layers as before, because the epidermis is continually replaced from underneath. Once this function is disturbed, we get hard and horny skin or abnormal flaking, with loose scales of dry, dead skin, as is so often the case with the scalp. If you wear the same underwear for too long, the offensive smell is due mainly to millions of dead skin cells and dried sweat.
