what is the lining of the mouth called
Oral mucosa 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.[1] The oral cavity has sometimes been described as a mirror that reflects the health of the individual.[2] 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.[3]
Pharynx The pharynx (plural: pharynges) is the part of the throat that is behind the mouth and nasal cavity and above the esophagus and the larynx, or the tubes going down to the stomach and the lungs. The pharynx is an area found in vertebrates and invertebrates, though the structure is not universally the same across all of those species.
