MICROANATOMY

Detailed explanation-1: -Stratified squamous epithelium: This type of epithelium usually has protective functions, including protection against microorganisms from invading underlying tissue and/or protection against water loss. The outer layer of your skin (the epidermis) is made of stratified squamous epithelial cells.

Detailed explanation-2: -Stratified epithelia contain two or more layers of cells. The function of this type of epithelium is mostly protective-the higher the number of layers, the more protective it is. It is good at withstanding abrasion. This type of epithelium is constantly renewing itself.

Detailed explanation-3: -keratin, fibrous structural protein of hair, nails, horn, hoofs, wool, feathers, and of the epithelial cells in the outermost layers of the skin. Keratin serves important structural and protective functions, particularly in the epithelium.
