Epithelium Mesodermal

Mesodermal epithelium: features of structure and function

Mesodermal epithelium, also known as coelodermal epithelium or coelonephrodermal epithelium, is one of three types of epithelium that arise from the germ layers of the embryo. It is formed from the mesoderm, one of the three germ layers, and performs important functions in the body.

The structure of the mesodermal epithelium is a layer of cells located on the basement membrane. The cells of this epithelium have different shapes and functions depending on their location and role in the body. They can be elongated and flat, cubic or cone-shaped.

One of the main functions of the mesodermal epithelium is the formation of the excretory system, which includes the kidneys, bladder and ureters. Mesodermal epithelial cells form canaliculi that filter the blood, removing waste and excess water from it. This allows you to maintain homeostasis in the body and get rid of toxins.

In addition, the mesodermal epithelium performs important functions in the development of the reproductive system. It forms the gonads - the ovaries in women and the testes in men. In addition, mesodermal epithelial cells are involved in the formation of gonadal glands, such as the prostate gland and seminal vesicles.

The mesodermal epithelium also plays an important role in the formation of the circulatory system. During embryonic development, cells of this epithelium migrate and form blood vessels and the heart.

In conclusion, the mesodermal epithelium is an important component of the body that performs many functions necessary to maintain life. Its unique structure and functions allow it to be an integral part of the development and functioning of various systems in the body.

Epithelial masses above the neural crest of the ectoderm and on the connective tissue of the body mesoderm. Located above the nerve of the mesenchymal embryo, they influence the formation of the nervous system and contribute to the development of the spinal cord. The source of their development are the cells of the supranervous primitive leaf. They correspond to some areas of the oral lick. Two types are described: E. mesodermal (under the influence of meningosal) and coelodermic (they suggest the existence of coelonervosis); in another way - coeloneurodermic. Impregnation is carried out - before nimnemin; embryonic experiments on blood transfusion and clicks indicate heterogeneity of clones.
