Examples of non-keratinized stratified squamous epithelium include some parts of the lining of oral cavity, pharynx, conjunctiva of eye, upper one-third esophagus, rectum, vulva, and vagina. Even non-keratinized surfaces, consisting as they do of keratinocytes, have a minor superficial keratinized layer of varying thickness, depending on the ...
Masticatory mucosa, keratinized stratified squamous epithelium, found on the dorsum of the tongue, hard palate, and attached gingiva. Specialized mucosa , specifically in the regions of the taste buds on lingual papillae on the dorsal surface of the tongue; contains nerve endings for general sensory reception and taste perception.
Keratin monomers assemble into bundles to form intermediate filaments, which are tough and form strong unmineralized epidermal appendages found in reptiles, birds, amphibians, and mammals. [ 3 ] [ 4 ] Excessive keratinization participate in fortification of certain tissues such as in horns of cattle and rhinos , and armadillos ' osteoderm . [ 5 ]

Non-keratinized squamous epithelium covers the soft palate, lips, cheeks and the floor of the mouth. Keratinized squamous epithelium is present in the gingiva and hard palate . [ 3 ] Keratinization is the differentiation of keratinocytes in the granular layer into dead surface cells to form the stratum corneum.
This specialization makes the epithelium somewhat water-resistant, so is found in the mammalian skin. The lining of the oesophagus is an example of a non-keratinized or "moist" stratified epithelium. [11] Parakeratinized In this case, the most apical layers of cells are filled with keratin, but they still retain their nuclei.
Non-keratinized squamous epithelium, including cornea and transitional epithelium [6] Cytokeratin 7: A subgroup of glandular epithelia and their tumors [6] Transitional epithelium and transitional carcinoma [6] Cytokeratin 8: Glandular epithelia of the digestive, respiratory and urogenital tracts, both endocrine and exocrine cells, as well as ...
