Final answer:
Stratified squamous epithelium is a protective tissue found in the body's areas exposed to abrasion and mechanical wear, such as the skin (keratinized), the mouth (non-keratinized), and the vagina (non-keratinized).
Step-by-step explanation:
Stratified squamous epithelium is a type of tissue that consists of multiple layers of cells, with the most apical layer composed of flat, scale-like cells. This tissue type is specially adapted for protection, as it shields underlying tissues from abrasion and forms a barrier against microbial invasion and water loss.
You would most likely find stratified squamous epithelium in areas of the body that are subject to wear and tear or where mechanical protection is important. Notably, this type of epithelium can be found in the skin, which is keratinized to prevent water loss and provide additional protection.
In contrast, non-keratinized stratified squamous epithelium is present in moist surfaces such as the lining of the mouth, which requires protection without the need for waterproofing, and in the vagina, which is also a site of potential friction and abrasion, hence the need for multiple cell layers.
