A stratified epithelium is an epithelium that is made up of a number of layers of cells. A stratified squamous epithelium is made up of a number of layers and the cells of the outer layers are flat (squamous).

In the deepest layer new cells are produced by the division of stem cells. Cells are gradually pushed toward the surface by the production of newer cells. Cells in the deep layers are basically cuboidal but become more and more flat as they are pushed toward the surface. Cells at the surface detach.

The arrow indicates the basal layer of the epithelium.
