The muscularis mucosae is the thin layer of smooth muscle found in most parts of the gastrointestinal tract located outside the lamina propria mucosae and adjacent to the submucosa.
It consists of several thin layers of smooth muscle fibers oriented in different ways which keeps the mucosal surface and underlying glands in a constant state of gentle agitation to expel contents of glandular crypts and enhance contact between epithelium and the contents of the lumen.
