MICROANATOMY

Detailed explanation-1: -Stratified squamous epithelium consists of a single basal layer containing stem cells, 2–3 layers of proliferative basaloid cells in the suprabasal region, and larger keratinized cells toward the surface. The esophageal squamous epithelium is nonkeratinizing, i.e., it does not have a stratum corneum.

Detailed explanation-2: -The stratified epithelium may be further classified based on the type of cells particularly at the surface: squamous, columnar, or cuboidal. A stratified squamous epithelium is a stratified epithelium in which the topmost layer is made up of squamous (flattened and scale-like) epithelial cells.

Detailed explanation-3: -Epithelia composed of a single layer of cells is called simple epithelia; epithelial tissue composed of multiple layers is called stratified epithelia.
