Excerpt from The Ready Reference Handbook of Diseases of the Skin The skin varies in thickness in different regions of the body from to 8 mm. It is composed of three distinct layers, namely: (1) the epidermis; (2) the derma, also named the cutis vera or corium; and (3) the subcuta neous connective tissue. At all the orifices of the body lined with mucous membrane, the latter and the skin merge into each other. The appendages of the skin are the hair, the nails, the sebaceous and the sweat glands. This complicated structure is supplied with bloodvessels, lymphatics, and nerves. About the Publisher Forgotten Books publishes hundreds of thousands of rare and classic books.
