Structure of skin
The skin has three layers of tissue: (1) epidermis, (2) dermis, and (3) subcutaneous tissue. The epidermis, the outermost layer, is about as thick as a sheet of paper over most parts of the body. The dermis, the middle layer, is between 15 and 40 times as thick as the epidermis. The subcutaneous tissue, the innermost layer, varies greatly in thickness among individuals. But in all people the subcutaneous tissue is much thicker than the epidermis and dermis. As well as these tissues, the skin includes the hair, nails, and certain kinds of glands.
