Shell Submucosa, Base Submucosa (Submucosa) is a layer of fibrous unformed connective (areolar) tissue, rich in elastic fibers, located under the mucous membrane (for example, in the intestinal wall). In the submucosa there are accumulations of lymphoid tissue, glands, submucosal nerve plexus, blood and lymphatic vessels.
The submucosa differs from the mucosa, which is the epithelial layer lining the cavities and channels that communicate with the external environment. Unlike the submucosa, the mucosa does not contain connective tissue, but consists of one or more layers of epithelium and secretes mucus. Thus, the submucosa is located deeper and performs a supporting function, and the mucous membrane lines the surface and secretes secretions.
Shell Submucosa, Base Submucosa (Submucosa): Structure and functions
The submucosa, also known as the submucosa, is an important layer in the walls of various organs, especially those of the digestive system such as the intestines. This layer consists of fibrous, unformed connective (areolar) tissue, rich in elastic fibers.
The structure of the submucosal membrane includes accumulations of lymphoid tissue, glands, submucosal nerve plexus, as well as blood and lymphatic vessels. This layer is located just below the mucous membrane and plays an important role in maintaining the structural integrity and function of organs.
One of the main functions of the submucosal membrane is to maintain nutrition and protection of the mucous membrane. Blood vessels passing through the submucosa provide oxygen and nutrients to the mucosa, allowing it to perform its functions effectively. In addition, lymphatic vessels in the submucosa are involved in immune defense, providing a process of filtration and removal of microorganisms and other harmful substances.
The submucosa also contains nerve endings that form the submucosal nerve plexus. This plexus plays an important role in regulating the motor function of organs and controlling excretory activity. It provides communication between the nervous system and organs, allowing them to effectively perform their functions.
In addition, the submucosa serves as support and protection for the mucous membrane. It provides structural support, ensuring stability and integrity of the mucous membrane during various motor functions of the organs.
In conclusion, the submucosa, or base submucosa, is an important layer in the walls of organs, especially in the organs of the digestive system. It provides support, protection and nutrition to the mucous membrane, and also plays an important role in regulating organ functions. Understanding the structure and function of the submucosal lining helps in understanding its importance in maintaining the health and normal functioning of the body.
Tunica submucosa and basal submucosa are two terms often used in the medical literature to describe the layer of fibrous, irregular connective tissue located beneath the mucosa, such as in the intestinal wall.
The submucous membrane usually consists of a layer of unformed fibrous connective tissue, which is rich in elastic fibers. It is located under the mucous membrane and provides mechanical support and protection to the internal organs. The submucosa may also be associated with glands and nerve plexuses.
The base submucosa is a layer of connective tissue that is located under the submucosal membrane. This layer is also rich in elastic fibers and contains clusters of lymphoid tissues, glands and nerve fibers.
