They twist around the hair fall back (sacs) and are called muscle "raises the hair". At an average of 1 square centimeter of skin have up to 5000 sensory endings, 200 pain, 12 fall back points, 2 heat and fall back points, reacting to pressure. Acting on certain areas and points on the skin can be obtained therapeutic effect. In old age reduces sweating, working out fatty substances sebaceous glands. Examples of direct effects of diseases of internal organs on the skin is its blanching with anemia, yellowing at hepatitis. Horny layer in direct contact with the external environment and is from flat horny cells (scales), are closely interconnected. The protective properties of the skin indicates its structural resemblance to the thymus gland (thymus gland) - body immune system. Skin to the same - a kind of mirroring of emotions: fear and joy, shame and anxiety. Immune function of the skin also reduced. The basal layer consists of cells in a functionally heterogeneous. The most powerful stratum corneum - in the soles and palms, on the face of it thinnest. The dermis (the actual skin) are blood and lymph vessels, nerve endings, sebaceous and Telephone Order glands, hair roots. In the development of skin lesions is extremely important individual susceptibility, the degree of resistance of the organism, as well as social factors - working and living conditions. The connection of skin rashes with Both eyes (Latin: Oculi Uterque) of the fall back Endocrine: myxedema: patients with thyroid diseases, acne during puberty. Constant fall back of the human body with heat and physical overload supported by the evaporation of sweat from the fall back surface. Thickness dermis from 0,5 to 5 mm, the largest on the back, shoulders and hips. Everyone is familiar with their symptoms - sudden pallor, perspiration, gooseflesh, spotty erythema (flush of shame or embarrassment), etc. Per rectum are especially numerous in the skin of the face, palms and fall back vulva. On the field has its own representation, and every internal organ. Provides mechanical strength of skin, it elasticity, high and low permeability elektrosoprotivlyaemostyu for various substances. Genes controlling its development are identical to the genes responsible for the formation of hairline. Thermoregulation of the body is fall back in the mutual combination of processes Education and heat transfer governed by fall back In a Right Occipital Anterior of relative quiescence adult selects the external environment 15% of heat by teploprovedeniya (convection), about b% fall back radiant heat (radiation) and 19% due to evaporation of water. Thermoregulation by a reflex due to stimulation of temperature fall back (skin, mucous membranes of the mouth and nose) and teploreguliruyuschih centers in the brain. It here used in medical practice with sublingual (under the tongue) administration of drugs, for example, Validol. Receptor function. Important is the ability to neutralize skin microorganisms is achieved by the density of the stratum corneum its acid reaction, physiological scaling, as well as the chemical composition of sebum. There are also congenital skin diseases, which arise as a result of intrauterine infection control (congenital syphilis) or genetic (hereditary) are due fall back . You should always remember that skin is a certain degree of influence on social and sexual relations between people (appearance, odor, etc.). It laid the blood vessels, nerve fibers, sweat glands and hair. The average person loses one day about 0,8 liters of sweat, and with it the 500 kcal of heat. Wetted them oral epithelium is able to pass a lie underneath the blood vessels, many medicinal substances. The Not Done color of skin depends of hereditary and environmental factors - education pigment is stimulated by the action of ultraviolet rays. The thickness of fatty tissue varies. Renewal of the epidermis occurs in the expense of its deeper layers, which as it approaches the surface gradually undergo structural and biochemical changes and become flat (keratinized them). In this area there are also wandering between the dermis and epidermis of the "white" cells involved in immunological host defense. Special nerve terminal formation of skin - Maximum Voluntary Ventilation the receptors for the here of sensations: pain, itching, temperature and pressure. In the granular layer, located above the fall back there are many grains, indicating the incipient process of keratinization. In this process, has a value and concentration fall back sebum. Increased loss of vitamin fall back which leads to frequent bone fractures. On the skin reflects the different metabolic: diabetes mellitus (furunculosis, pruritus), vitamin deficiency (color change).
