Lining mucosa, nonkeratinized stratified squamous epithelium, found almost everywhere else in the oral cavity, including the: Alveolar mucosa , the lining between the buccal and labial mucosae. It is a brighter red, smooth, and shiny with many blood vessels, and is not connected to underlying tissue by rete pegs .
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 ...
With the advancement of tissue engineering an alternative approach was developed: the full-thickness engineered oral mucosa. Full-thickness engineered oral mucosa is a better simulation of the in vivo situation because they take the anatomical structure of native oral mucosa into account. Problems, such as tissue shortage and donor site ...
A mucogingival junction is an anatomical feature found on the intraoral mucosa. The mucosa of the cheeks and floor of the mouth are freely moveable and fragile, whereas the mucosa around the teeth and on the palate are firm and keratinized. Where the two tissue types meet is known as a mucogingival junction.
Major aphthous ulceration usually affects non-keratinized mucosal surfaces, but less commonly keratinized mucosa may also be involved, such as the dorsum (top surface) of the tongue or the gingiva (gums). [9] The soft palate or the fauces (back of the throat) may also be involved, [9] the latter being part of the oropharynx rather than the oral ...
Alveolar mucosa is non keratinized oral epithelium and is located apical to the keratinized tissue, delineated by the mucogingival junction (MGJ). It should also be pointed out that mucosa can surround a tooth in health. [4] Nonkeratinized tissue also lines the cheeks (buccal mucosa), underside of the tongue and floor of the mouth.
Please help improve it to make it understandable to non-experts, without removing the technical details. ( March 2019 ) ( Learn how and when to remove this message ) In dental anatomy , the junctional epithelium ( JE ) is that epithelium which lies at, and in health also defines, the base of the gingival sulcus (i.e. where the gums attach to a ...
Because of the differences between mucous membranes and the skin (e.g., keratinizing mucosa does not have a stratum lucidum and non keratinizing mucosa does not have this layer or normally a stratum corneum or a stratum granulosum), sometimes specialized texts give slightly different definitions of hyperkeratosis in the context of mucosae.
