  2. Detrusor muscle - Wikipedia

    en.wikipedia.org/wiki/Detrusor_muscle

    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.

  3. Muscular layer - Wikipedia

    en.wikipedia.org/wiki/Muscular_layer

    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.

  4. Gastrointestinal wall - Wikipedia

    en.wikipedia.org/wiki/Gastrointestinal_wall

    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.

  5. Lamina propria - Wikipedia

    en.wikipedia.org/wiki/Lamina_propria

    The lamina propria may also be rich in vascular networks, lymphatic vessels, elastic fibers, and smooth muscle fascicles from the muscularis mucosae. Afferent and efferent nerve endings can be found in the lamina propria as well. [6] Immune cells as well as lymphoid tissue, including lymphoid nodules and capillaries, may be present.

  6. Diverticulum - Wikipedia

    en.wikipedia.org/wiki/Diverticulum

    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.

  7. Ureter - Wikipedia

    en.wikipedia.org/wiki/Ureter

    The lamina propria is made up of loose connective tissue with many elastic fibers interspersed with blood vessels, veins and lymphatics. The ureter is surrounded by two muscular layers, an inner longitudinal layer of muscle, and an outer circular or spiral layer of muscle.

  9. Rectum - Wikipedia

    en.wikipedia.org/wiki/Rectum

    The microanatomy of the wall of the rectum is similar to the rest of the gastrointestinal tract; [9] namely, that it possesses a mucosa with a lining of a single layer of column-shaped cells with mucus-secreting goblet cells interspersed, resting on a lamina propria, with a layer of smooth muscle called muscularis mucosa.
