Anatomical terminology [edit on Wikidata]

The submucosa (or tela submucosa) is a thin layer of tissue in various organs of the gastrointestinal, respiratory, and genitourinary tracts. It is the layer of dense irregular connective tissue that supports the mucosa (mucous membrane) and joins it to the muscular layer, the bulk of overlying smooth muscle (fibers running circularly within layer of longitudinal muscle).

The submucosa (sub- + mucosa) is to a mucous membrane what the subserosa (sub- + serosa) is to a serous membrane.
