Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]

On the specimen ofthe soft palate the oral and nasal surfaces were observed. The epithelium on the mouth surface is damaged. What type of epithelium is damaged?

A	Simple squamous
B	Pseudostratified columnar ciliated
C	Simple cuboidal
D	Stratified squamous non-keratinised
E	Stratified cuboidal

Explanation:

Detailed explanation-1: -The entire surface of the oral mucosa is covered by squamous stratified epithelium. This is a highly organized, avascular, and semipermeable tissue whose thickness and degree of keratinization varies according to the location in the oral cavity and the area’s functional and mechanical requirements.

Detailed explanation-2: -The lower surface of the hard palate faces the oral cavity and is lined by stratified squamous epithelium. This type of epithelium characterizes the upper gastrointestinal tract, including the mucosa of the esophagus as well as the oral cavity. The mucosa of the palate includes salivary glands.

Detailed explanation-3: -non-keratinized stratified squamous. The type of epithelium that lines the oral cavity is the non-keratinized stratified squamous epithelium. The non-keratinized stratified squamous epithelium consists of many layers of cells that are cube-shaped in the basal layer and progressively flattened toward the surface.
