The skin is divided into two main regions, the epidermis, and the dermis, one of each providing a distinct overall role function of the skin. The dermis is mainly attached to an underlying hypodermis, which is also called subcutaneous connective tissue, which generally stores adipose tissue and also recognized as the superficial fascia of gross anatomy. Basically it is composed of three layers. The outer-most layer is called the epidermis, which serves as a barrier and protects the body from any infection. The second layer is called the dermis and consists of connective tissues which cushion the body from stress and strain.
