Detailed explanation-1: -A stratified squamous keratinized epithelium is found on surfaces subject to the abrasion that occurs with mastication, e.g., the roof of the mouth (palate) and gums (gingiva).

Detailed explanation-2: -Attached gingiva is a type of masticatory mucosa, lined with a para-keratinized stratified squamous epithelium. The increased amount of keratin, compared to alveolar mucosa, obscures the underlying blood supply, creating a lighter appearance (which can be described as whitish in the absence of melanin).

Detailed explanation-3: -The parakeratinized epithelium covers the dorsal surface of the tongue, responsible for the passive transport of food to the esophagus (Iwasaki et al.

Detailed explanation-4: -Masticatory and lingual mucosa are surfaced by a parakeratinized epithelium, which lacks a prominent granular layer and covers regions exposed to strong shear forces such as the tongue, attached gingiva, and hard palate.
