The inguinal skin

occurs on the fingers, the palm (palmar) and the sole of the foot (plantar) on. The epidermis shows here fine ridges (epidermal ridges), arising from the fact that the dermal papillae arranged in longitudinal rows. It all skin bar is underlain by two Papillarkörperreihen. The dermal ridges form an individual pattern of various geometric figures (vertebral arch, loop, double loop). These patterns are used in the fingerprint (fingerprint recognition) forensic technology as a form of biometric data. The inguinal skin contains, besides many sweat glands, no skin appendages.

Fields skin

covered the remaining areas of skin. Here, the surface shows fine grooves bounded by rhombic fields (areolae cutanea). The furrows occur on the papillae Epidermisbereichen and spread at a higher skin tension. They serve as a reserve wrinkles, because the epidermis is less stretchable than the dermis. The size of the skin fields varies depending on the body. The boxes containing the skin and subcutaneous tissue less than 1 / 10 mm thick. It is the thinnest in the area of the eye and the genital organs.

parts of the skin and its functions

The skin protects against heat loss and external influences, and is used to hold contact stimuli. In addition, to meet the individual components of specialized functions:

* hair: protection against heat loss and solar radiation
* horny layer: protection from injuries and dehydration
* seed layer: Rebuilding of skin cells *
melanocytes: the protection of genetic information in the nucleus from UV radiation
* free Nerve endings: Admission of touch and pain stimuli
* lamellar bodies: receiving pressure stimuli
* sweat glands: Production of welding, protection against overheating due to evaporation
* cold receptors: Admission of temperature stimuli "cold"
* heat receptors: recording of temperature stimuli "warm"
* Haarbalgmuskel: heat storage by raising the vellus
* Sebaceous gland: production of sebum (grease) *
corpuscles: Admission of touch stimuli
* fat storage: protection against pressure and hypothermia
* Blood vessels: temperature regulation and supply the skin cells with nutrients and oxygen
