Muscular

The muscular layer is part of the wall of hollow organs such as the stomach, intestines or ureters. It consists of smooth muscle cells and is responsible for peristalsis and contraction of these organs.

The muscle layer is divided into two sublayers - the outer longitudinal and the inner circular. The longitudinal layer consists of bundles of smooth muscle fibers running along the organ. The circular layer is located under the longitudinal one and consists of circular muscle fibers. The contraction of these muscles ensures mixing and movement of the contents of the hollow organ.

In addition, the mucous membrane of hollow organs has its own thin layer of smooth myocytes - the muscular plate of the mucous membrane. It is responsible for local contraction and thickening of the mucosa.

Thus, the muscle layer plays an important role in the functioning of the hollow organs, providing their contractility. The structure and orientation of muscle fibers is optimized to perform specific movements in each specific organ.

The muscular layer of the organ wall, also known as muscularis, is an important element in the functioning of the gastrointestinal tract. It causes the walls of the hollow organ to contract and expand, allowing food and other substances to move within the body.

Muscular (Muscularis) are the muscular layers of the wall of a hollow or tubular organ of the gastrointestinal tract. They form the outer strong frame of the organs. These are smooth fibers that cannot contract in isolation. Their motor ability is the result of excitation of the skeletal muscles, which they are innervated by the autonomic nervous system. Any disturbances in the motility of the muscle layer or its condition lead to defects in the motor activity of the gastrointestinal and excretory tract. The muscular plate of the mucous membrane is given the term Muscularis Mucosae. It assumes the presence of a multilayer muscle layer, consisting of several layers
