Splanchnopleure

The splanchnopleura is the intestinal wall of the embryo, consisting of a layer of endoderm covered on the outside by a layer of mesoderm. The yolk sac is a continuation of this structure.

The splanchnopleura forms the intestinal tube of the embryo and the organs of the digestive, respiratory and urinary systems. The endoderm gives rise to the epithelial lining of these organs, and the mesoderm gives rise to their connective tissue and muscle components.

Unlike the splanchnopleura, the somatopleura forms the body wall of the embryo and gives rise to the skin, skeleton and muscles. Thus, the splanchnopleura and somatopleura are complementary structures that form the internal organs and outer integument of the embryo, respectively.

Splanchnopleure is an embryonic layer of tissue that forms the intestinal wall and yolk sac in vertebrates. This layer has two components: endoderm and mesoderm.

Endoderm is the inner layer of embryonic tissue that forms the inner lining of the digestive, respiratory and urinary systems. In the case of splanchnopleura, the endoderm forms the inner lining of the intestine and yolk sac.

Mesoderm is the middle layer of embryonic tissue that develops between the endoderm and ectoderm (outer layer). In the case of splanchnopleura, the mesoderm forms the outer covering of the intestine and yolk sac.

The splanchnopleura is an important component of the early development of the embryo, as it forms the basis for the formation of the gastrointestinal tract. This process begins with the formation of the intestinal tube, which then differentiates into various organs of the digestive system.

Compared with Somatopleura, which forms the outer covering of the body of the embryo and develops in the mesoderm, Splanchnopleura has a large role in the formation of the organ system of the internal cavity of the body. Both layers are important components of the early development of the embryo and interact to form various organs and tissues.

In conclusion, the splanchnopleura is an important component of embryonic development that forms the intestinal wall and yolk sac. It consists of two components - endoderm and mesoderm - and plays a key role in the formation of the organ system of the internal cavity of the body.

Splanchnopeura is an intestinal wall that has a simpler structure compared to the three adjacent layers, as well as a yolk sac.

> Features of development. The fetal fluid is first segregated and has a segment at its base surrounded by a strip of connective tissue membrane 20-50 µm thick. The ventilatory field of the intestinal endoderm, from where the migration of pricinocytes occurs, takes part in the formation of FM. Migrating cells retain the original connection with the ectoderm and a consistent modification of intercellular connections in each cell layer
