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: -Stratified squamous epithelium is limited to the esophagus in the human foregut.

Detailed explanation-3: -Besides the skin, the keratinized stratified squamous epithelium is also found in areas of the oral mucosa that are subject to frictional stress, such as the gingiva, hard palate and parts of the tongue. The keratinized epithelium in the oral mucosa is similar to the epidermis, except that it lacks the stratum lucidum.
