The mucosa is divided into three layers: epithelium, lamina propria, and muscularis mucosae. The epithelium is the outermost layer, followed by the lamina propria, which is a thin layer of connective tissue. The muscularis mucosae is the innermost layer, consisting of smooth muscle cells that help with movement and function of the mucosa.
The subdivisions of the wall layer muscularis externa are the longitudinal layer, circular layer, and oblique layer.
The third layer, the obliquely oriented layer, of smooth muscle in its muscularis externa allows the stomach to churn, mix, and pummel the food, physically reducing it into smaller pieces.
Muscularis propria is a layer of smooth muscle found in the gastrointestinal tract. It is located between the mucosa and the submucosa, and its main function is to provide motility for the movement of food through the digestive system.
The muscularis layer of arteries has a thicker layer of smooth muscle.
The muscularis externa is the layer of the digestive tube, which consists of smooth muscles. It mixes ingested food with gastric juices so digestion is able to occur.
the smooth muscles are responsible for perstalsis and segmentation, so that means its the muscularis externa. :)
