Organizational structure
Skin is divided into two main classes. Layer closest to the surface is known as the epidermis and the layer below is called packaging.

Epidermis contains three types of cells. Surface flat cells, called squamous cells. Under layers of squamous cells are round cells called cell base. Between cells is the basis of melanocytes.

Envelope containing nerve endings, blood vessels, oil and sweat glands. It was held together by a protein called collagen.
