The oral mucosa is the mucous membrane lining the inside of the mouth and consists of stratified squamous epithelium termed oral epithelium and an underlying connective tissue termed lamina propria.〔Ten Cate's Oral Histology, Nanci, Elsevier, 2013, page 280〕 The oral cavity has sometimes been described as a mirror that reflects the health of the individual. Changes indicative of disease are seen as alterations in the oral mucosa lining the mouth, which can reveal systemic conditions, such as diabetes or vitamin deficiency, or the local effects of chronic tobacco or alcohol use. ==Classification== It can be divided into three main categories based on function and histology: *Masticatory mucosa, keratinized stratified squamous epithelium, found on the dorsum of the tongue, hard palate and attached gingiva. *Lining mucosa, nonkeratinized stratified squamous epithelium, found almost everywhere else in the oral cavity, including the: * *Buccal mucosa refers to the inside lining of the cheeks and is part of the lining mucosa. * * Labial mucosa refers to the inside lining of the lips and is part of the lining mucosa. * *Alveolar mucosa refers to the mucosa between the gums and the buccal/labial mucosa. *Specialized mucosa, specifically in the regions of the taste buds on lingual papillae on the dorsal surface of the tongue that contains nerve endings for general sensory reception and taste perception.〔University of Michigan Health System, Learning Resource Center at http://histology.med.umich.edu/node/2〕 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Oral mucosa」の詳細全文を読む スポンサード リンク
