The detrusor muscle, also detrusor urinae muscle, muscularis propria of the urinary bladder and (less precise) muscularis propria, is smooth muscle found in the wall of the bladder. The detrusor muscle remains relaxed to allow the bladder to store urine , and contracts during urination to release urine.
The muscular layer (muscular coat, muscular fibers, muscularis propria, muscularis externa) is a region of muscle in many organs in the vertebrate body, adjacent to the submucosa. It is responsible for gut movement such as peristalsis. The Latin, tunica muscularis, may also be used.
The muscular layer (also known as the muscularis propria [8]) consists of two layers of muscle, the inner and outer layer. The muscle of the inner layer is arranged in circular rings around the tract, whereas the muscle of the outer layer is arranged longitudinally.
True diverticula involve all layers of the structure, including muscularis propria and adventitia, such as Meckel's diverticulum. [2] True diverticula are typically synonymous with traction diverticula, which describes the mechanism of formation as pulling forces external to the structure.
Underlying the epithelium is the lamina propria, which contains myofibroblasts, blood vessels, nerves, and several different immune cells, and the muscularis mucosa which is a layer of smooth muscle that aids in the action of continued peristalsis and catastalsis along the gut.

Adenocarcinoma is a malignant epithelial tumor, originating from superficial glandular epithelial cells lining the colon and rectum. It invades the wall, infiltrating the muscularis mucosae layer, the submucosa, and then the muscularis propria. Tumor cells describe irregular tubular structures, harboring pluristratification, multiple lumens ...
Gallbladder adenomyomatosis is a benign disease of the gallbladder characterized by hyperplasia of the mucosal epithelium and smooth muscle cells inside the muscularis propria. [ 4 ] [ 5 ] [ 6 ] The excessive proliferation of epithelial cells causes the mucosa to invaginate into the muscular layer lining the gallbladder wall, resulting in ...
