Question

Match the following epithelial tissue with a body location where it can be found: Keratinized stratified squamous?

1) Skin
2) Lining of the mouth
3) Lining of the esophagus
4) Lining of the vagina

Answer 1

Keratinized stratified squamous epithelium is found in the skin, where it serves as a protective layer against abrasion and microbial invasion. It makes up the cutaneous membrane that covers the body's exterior.

Step-by-step explanation:

The keratinized stratified squamous epithelium is a type of epithelial tissue found in areas of the body where protection against abrasion is necessary. This tissue is characterized by multiple layers of cells, with the most superficial layers being dead and filled with keratin, a protective protein. The primary locations where one would find keratinized stratified squamous epithelium are the skin and in certain body openings that are exposed to the external environment, where it serves as a barrier against physical and microbial injury. Specifically, this tissue is found in the skin and also forms the epithelial membrane, also known as the cutaneous membrane. It rests on top of connective tissue with an apical surface exposed to the external environment.
