Keratinized Oral Mucosa
Keratinization of stratified squamous epithelium may occur at sites in the oral cavity where the mucosa is subjected to habitual mechanical stress - such as continuous trauma from chewing. This response is similar to the formation of a callus on the hands of a manual laborer. Note the typical appearance of the stratum corneum (A). No nuclei are visible in contrast with the parakeratinized variety. Re-identify the other structures labelled.
