Answer: A many-layered epithelium with cuboidal basal cells and flat cells at its surface would be classified as stratified squamous epithelium.
Explanation:
Tissues composed of multiple squamous cell layers on a basement membrane are called epithelia. Layered in <em>uninterrupted sheets, </em>the cell layers are found throughout the body in exposed areas and internal organs.
The flat basal cells found on the basement membrane divide and differentiate, to <em>form cuboidal or columnar cells</em>; these are typically underneath the squamous cells layers and are layered related to their degree of <em>differentiation.</em>
