Some stratified squamous epithelia are extensively keratinized, whereas others are keratinized either minimally or not at all. A typical example of stratified squamous keratinized epithelium is the epidermis. The stratified squamous epithelium consists of several layers of cells, where the cells in the apical layer and several layers present deep to it are squamous, but the cells in deeper layers vary from cuboidal to columnar.
Histopathological examination showing keratinized
In the deep layer of stratified squamous epithelium, you will find the columnar epithelium that rests on the basement membrane.
It is named for the shape of the cells on the surface of the tissue.
Cuboidal or columnar cells may be seen in the deeper layers.
