Skin area of connective tissue below the [[Cutis/en|cutis], in which the blood vessels and nerves supplying the skin lie. The subcutis represents the connection to structures under the skin such as bones or fasciae (surrounding the muscles).
The subcutis is a fat store and insulator. It contains - especially in the hand and the sole of the foot - the Vater-Pacini lamellar bodies, which serve the sensation of vibrations. In the peripheral part of the subcutis, the vessel-gland layer, the stratum glandulovasculare, lie the end pieces of the sweat glands and the larger skin vessels. They provide the mesh of arteries of the corium with blood.
The fatty tissue of the subcutis is very strongly capillarized. In the case of obesity, this represents a great strain on the circulation.
