Question

A many-layered epithelium with cuboidal basal cells and flat cells at its surface would be classified as ________.

Answer 1

A many-layered epithelium with cuboidal basal cells and flat cells at its surface is classified as stratified squamous epithelium, which provides protection from abrasion and is found in areas like the skin, mouth, and vagina.

Step-by-step explanation:

A many-layered epithelium with cuboidal basal cells and flat cells at its surface would be classified as stratified squamous epithelium. This type of tissue consists of multiple layers of cells, with the most superficial or apical layer being flat, scale-like cells, known as squamous cells. Below the squamous cells are layers of cuboidal cells that do not reach the surface but are attached to the underlying basal lamina. This configuration provides a protective function, as the outermost squamous cells can help protect the underlying tissues from abrasion and injury.

For example, in the epidermis of the skin, the basal layer of the epidermis consists of cuboidal cells, which give rise to the outer layers of flattened squamous cells that are keratinized. In tissues lining body surfaces such as the mouth and vagina, stratified squamous epithelium also plays a role in protecting these areas from damage.

Answer 2

Answer: A many-layered epithelium with cuboidal basal cells and flat cells at its surface would be classified as stratified squamous epithelium.

Step-by-step explanation:

Tissues composed of multiple squamous cell layers on a basement membrane are called epithelia. Layered in uninterrupted sheets, 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 form cuboidal or columnar cells; these are typically underneath the squamous cells layers and are layered related to their degree of differentiation.
