What is the skin?Schematic representation of the anatomy and structure of the skin. The skin is a sensitive organ. Daily care and medical care help against skin aging and skin diseases. Click to enlarge.
The skin is a natural shell, which consists of several layers. It not only surrounds the externally visible part of the body. The skin is an organ that also lines or envelops many internal organs. It is also known as cutis or derma in medicine.
On the skin is a visible layer of microorganisms, which is technically properly called skin flora. An intact skin flora is the prerequisite for healthy skin and its unrestricted functioning as well as beauty. In addition, the skin, like any organ, is subject to natural aging processes and can develop various influences.
Anatomy & Construction
Surely many people already know that the skin is a complex of different layers, which in turn consist of different tissues and these in turn of varying cells. If the skin were to be cut, the outer skin layer could be the epidermis in episode first.
Under this is the second layer of the skin, the dermis, whose name Corium is also correct. The lowest layer of the skin is the subcutaneous or sub (sub) cutis. Within the structures of the skin is still another anatomical medium recognizable. The fibrous collagen substance gives the skin its limited elasticity and resistance.
The individual layers of the skin are preserved for a lifetime. The skin is renewed by the fact that the skin cells, which have calloused and are no longer functional, simply fall off.
Functions & Tasks
The function of the skin depends on several areas. The natural shell holds the entire body inside and out and also provides a whole range of protective functions.
If the skin is intact, this is considered an ideal shield against low and high outside temperatures. The skin thus assumes a significant share in the context of the "air conditioning" of the organism. It can give off excess energy when overheating and retain the heat when it is undercooled. The skin is thus an important temperature regulator.
The skin provides further protection against UV radiation, against mechanical influences and chemical substances. In addition, the skin is used to some extent as a "goat" and for moistening in the form of the mucous membranes. In addition, the skin provides a natural barrier to the loss of fluid and prevents access of microorganisms.
Within the sensory organs, the human being is able to feel movements and pain through the skin via the receptors in the nerves. Temperature differences and different pressures are received through the skin. The skin is used as a feeler while touching. In addition, the skin is constantly busy with their repair.
As reliable as the skin is, it is equally vulnerable. A whole range of skin diseases are treated in dermatology. These include both acquired during life and congenital defects of the skin or diseases.
Skin diseases are characterized by various complaints such as dandruff, irritating itching, redness, scabbing, oozing, wheals, papules, pustules and rash. Shingles, atopic dermatitis, psoriasis, acne, fungal diseases, heroes, eczema, warts and the fire potion are among the classic diseases of the skin. The individual skin diseases are characterized by different courses and show a more or less good prognosis.
The skin is extremely sensitive to abnormal changes in the organism. These can lead to skin on physical or mental impairments to diseases. The vaginal fungus, thrush, hyperhidrosis and hair loss are also considered to be skin disorders. Individual diseases of the skin refer in particular to the mucous membranes or only special skin tissues.
A variety of skin diseases can be hereditary or genetic. In addition, some skin discomfort does not develop until adulthood.
