Epidermis - The structure fo skin that contains tightly packed epithelial cells arranged in many different layers. The innermost layer being the stratum germinativum where the cells of the innermost layer of the epidermis reproduce themselves via mitosis. As cells from the stratum germinativum move towards the surface of the skin, the cells cytoplasm is replaced with keratin. Keratin is a protein substance that is tough and waterproof. This substance provides cells on the outer layer of skin with a horny, abrasion-resistant, protecive quallity.
