3. Name the three layers of the skin and give a brief description of each layer.

Epidermis- the outermost layer which depending on the body location has several layers. The stratum coreum which is thinnest outermost layer consisting of dead keratinized cells protect underlying cells and tissue from dehydration and stop entry of certain chemicals agents. The stratum basale where the cells divide, proliferate and migrate towards the epidermal surface continually ensuring replacement of cells sloughed off during normal shedding. (Crisp, Taylor, Douglas, & Rebeiro, 2013, p. 754)

Dermis-Middle layer that mainly contains connective tissue and a few skin cells, which provides the tensile strength, mechanical support and protection to the underlying muscles, bones and organs. (Crisp, Taylor, Douglas, & Rebeiro, 2013, p. 758)

Hypodermis-The bottom and thickest layer of the skin, which is made up of adipose, connective tissue and blood vessels. It provides a support framework for the skin and attachment and is a protective layer for the underlying organs and structures. (Crisp, Taylor, Douglas, & Rebeiro, 2013, p. 758)
