The nerves of the skin

The skin contains blood vessels and sensory, motor, vasomotor, and secretory sympathetic nerves. The end of the sensory nerves are located in the epidermis, due to them by the perception of pain. Tactile corpuscles, Meissner corpuscles or (corpuscula tactus), buds are in the dermis, are oval in shape and surrounded by a connective tissue sheath. Their greatest number occurs in the fingertips, palmar surface of hands and the soles. These cells perceive touch. Tactile menisci - Merkel discs - are located in the lower layers of the epidermis, composed of epithelial cells and sensory nerve endings. They also perceive touch and form a zone of high sensitivity (for example, a lot of them in his mouth). Exposure to heat Ruffini corpuscles perceive, and the cold - end bulb. In the subcutaneous tissue are larger (2 to 4 mm), oval plate cells Vater - Pacini (corpuscula lamellosa), which can not only transmit information to the brain about touch, but also to assess the degree of pressure, causing the body responds to vibration.
