GROSS ANATOMY

Detailed explanation-1: -Histologically, the oral mucosa is formed by three layers, a surface squamous stratified epithelium, known as the oral epithelium, whose thickness and degree of keratinization depend on the location and functional requirements .

Detailed explanation-2: -These cells appear larger or plumper than the basal layer cells, because they have larger amounts cytoplasm. The cells of the intermediate layer have lost the ability to undergo mitosis as they migrated. The intermediate layer makes up the bulk of nonkeratinized epithelium.

Detailed explanation-3: -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-4: -Masticatory mucosa, keratinized stratified squamous epithelium, found on the dorsum of the tongue, hard palate, and attached gingiva.
