Assuming you mean muscularis, it's a part of the layers found around our Gastrointestinal system and other systems in our body (Reproductive tract etc).
The 4 layers are:
1. mucosa (epithelial layer)
2. submucosa
3. muscularis
4. serosa
Muscularis has both longitudinal and circular muscle layers (in the GI tract this is smooth muscle which is used for peristalisis, haustration, etc). Muscularis layer is contractile and used in the GI tract for moving food through the system, or in the reproductive tract for contractions for birth, etc.
Hope this helps?
muscularis
the smooth muscles are responsible for perstalsis and segmentation, so that means its the muscularis externa. :)
The four histological layers of the gut are the mucosa, submucosa, muscularis externa, and serosa (or adventitia). The mucosa is the innermost layer, containing epithelial cells and glands. The submucosa provides support and contains blood vessels and nerves. The muscularis externa is responsible for peristalsis, and the serosa (or adventitia) is the outermost layer providing protection and support.
The correct order of the layers of the gastrointestinal tract wall from lumen to external surface is mucosa, submucosa, muscularis externa, and serosa (or adventitia depending on the location in the body).
The epithelium, lamina propria, and muscularis mucosae are levels of the mucosa, which is the innermost layer of the gastrointestinal (GI) tract. The mucosa is responsible for absorption and secretion.
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.
muscularis
The subdivisions of the wall layer muscularis externa are the longitudinal layer, circular layer, and oblique layer.
the smooth muscles are responsible for perstalsis and segmentation, so that means its the muscularis externa. :)
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.
tunica mucosa, muscularis, adventitia
The four histological layers of the gut are the mucosa, submucosa, muscularis externa, and serosa (or adventitia). The mucosa is the innermost layer, containing epithelial cells and glands. The submucosa provides support and contains blood vessels and nerves. The muscularis externa is responsible for peristalsis, and the serosa (or adventitia) is the outermost layer providing protection and support.
muscularis
Smooth Muscle - Muscularis Mucosa

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.
