Stratified squamous epithelium.

This epithelium is similar to the keratinized stratified squamous epithelium but it has no stratum corneum. Once the contact to the basal lamina is lost, basal stratum cells change from rounded to flattened shapes, as they travel toward the surface of the epithelium, but they do not form a corneum stratum. They detached directly from the stratum granulosum. Stratified squamous epithelium can be found in other body surfaces such as oral cavity and vagina. Nearby gland secretions maintain the free surface wet. That is why protection of the corneum stratum against water loss is not needed (the location of this epithelium in inner organs helps avoid drying). However, to avoid mechanical injuries, the esophagus of some rodent species that feed hard food shows stratum corneum.
