The skin is the largest of all human organs. Its surface area is between  1.5 and 2 m2. This is about 1/6th of total weight of the body.

It is the outer covering of the body. It is disposed in two layers

bullet

Epidermis (outermost)

bullet

Dermis (innermost)


Below the skin is the layer of superficial and deep fasciae.

Skin has condensation of collagen fibers in lines which are called Langer's lines. These lines heal with minimum scarring when surgical incisions are made along their courses (e.g. Pfannenstiel incision).

Skin is supplied by cutaneous nerves and vessels and drained by cutaneous veins.
