The lamina muscularis mucosae (or muscularis mucosae) is a thin layer (lamina) of muscle of the gastrointestinal tract, located outside the lamina propria, and separating it from the submucosa. (wikipedia.org)
With newer advances in techniques for endoscopic mucosal resection (EMR) [ 11 ] and ablation (radiofrequency and cryotherapy), assessing the depth of invasion of mucosal cancers is vital, with a pivotal role for OCT. Indeed, studies have shown superiority of resolution for OCT compared to EUS specifically for visualization of the mucosa and submucosa [ 12 ]. (hindawi.com)

In patients with small, discrete nodules or areas of dysplasia in whom disease appears limited to the mucosa or submucosa as assessed by endoscopic ultrasonography, endoscopic mucosal resection should be considered as a diagnostic/staging tool. (medscape.com)
The etymology suggests this, since the Latin names translate to "the mucosa's own special layer" (lamina propria mucosae) and "muscular layer of the mucosa" (lamina muscularis mucosae). (wikipedia.org)

The mucosa is densely packed with gastric glands, which contain cells that produce digestive enzymes, hydrochloric acid, and mucus.The muscularis has three layers of muscle: an outer longitudinal layer, a middle circular layer, and an inner oblique layer. (britannica.com)
Epithelium2
The muscularis mucosae is composed of several thin layers of smooth muscle fibers oriented in different ways which keep 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. (wikipedia.org)
The inner mucosal layer consists of squamous epithelium and underlying connective tissue, within which lies a longitudinally oriented muscle layer called the muscularis mucosa. (nature.com)
