The lamina muscularis mucosae (or muscularis mucosae) is the thin layer of smooth muscle found in most parts of the gastrointestinal tract located outside the lamina propria mucosae and separating it from the submucosa. In the gastrointestinal tract the term mucosa or mucous membrane refers to the combination of epithelium lamina propria and (where it occurs) muscularis mucosae.
