Non-keratinized surfaces must be kept moist by bodily secretions to prevent them from drying out. Cells of stratum corneum are sometimes without keratin and living. 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 ...
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.
Keratinized squamous epithelium is present in the gingiva and hard palate as well as areas of the dorsal surface of the tongue. [ 8 ] [ 9 ] Keratinization is the differentiation of keratinocytes in the stratum granulosum into nonvital surface cells or squames to form the stratum corneum.
The soft tissue in the oral cavity is classified as either keratinized or nonkeratinized based on the presence of keratin in the epithelium. [3] In health, the soft tissue immediately around the teeth is keratinized and is referred to as keratinized tissue or gingiva. Alveolar mucosa is non keratinized oral epithelium and is located apical to ...
Stratified squamous, non-keratinized - reproductive - female: vaginal epithelium: Stratified squamous, non-keratinized - reproductive - female: labia majora: Stratified squamous, keratinized - reproductive - male: tubuli recti: Simple cuboidal: germinal epithelium (male) reproductive - male: rete testis: Simple cuboidal - reproductive - male ...
Epithelium lines both the outside and the inside cavities and lumina of bodies. The outermost layer of human skin is composed of dead stratified squamous, keratinized epithelial cells. [14] Tissues that line the inside of the mouth, the esophagus, the vagina, and part of the rectum are composed of nonkeratinized stratified squamous epithelium ...
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 ...
The transitional epithelium cells stretch readily in order to accommodate fluctuation of volume of the liquid in an organ (the distal part of the urethra becomes non-keratinized stratified squamous epithelium in females; the part that lines the bottom of the tissue is called the basement membrane).
