Detailed explanation-1: -The stratified epithelium is named by the shape of the most apical layer of cells, closest to the free space. Stratified squamous epithelium is the most common type of stratified epithelium in the human body. The apical cells are squamous, whereas the basal layer contains either columnar or cuboidal cells.
Detailed explanation-2: -The apical surface of epithelial cells, which lines the lumen of sac-and tube-shaped organs and the inner surfaces of the body cavities, forms the interface between the extracellular milieu and underlying tissues.
Detailed explanation-3: -Most epithelial tissue is described with two names. The first name describes the number of cell layers present and the second describes the shape of the cells. For example, simple squamous epithelial tissue describes a single layer of cells that are flat and scale-like in shape.
Detailed explanation-4: -Based on the shape of cells, epithelial tissues have three types of cells: they are squamous, cuboidal, and columnar.
