A lining of mostly endodermal origin, covered in epithelium, which is involved in absorption and secretion. They line various body cavities that are exposed to the external environment and internal organs. It is at several places continuous with skin: at the nostrils, the lips, the ears, the genital area, and the anus. The sticky, thick fluid secreted by the mucous membranes and gland is termed mucus. The term mucous membrane refers to where they are found in the body and not every mucous membrane secretes mucus[WP]. [ http://en.wikipedia.org/wiki/Mucous_membrane ]

FMA has mucosa vs region of mucosa; these are subtypes of Mucosa: Mucosa of gallbladder, tongue, .... The following are subtypes of Region of mucosa: Mucosa of zone of stomach, trachea, bronchus, dorsum of tongue.... Depends on whether the covered area is an organ or organ component. Uberon does not regard organ vs organ component as crucial distinction and thus collapses these into a single class deliberately
