Somatic mesoderm (m. somaticum) is a layer of mesoderm that is located between the dermis and hypodermis. It provides communication between these layers, and also participates in the formation of connective tissue, blood vessels and nerves.
Somatic mesoderm has several functions. Firstly, it participates in the formation of the dermis and hypodermis. Secondly, it provides support and protection for these layers. Thirdly, it plays a role in regulating metabolism and homeostasis of the body.
In addition, the somatic mesoderm is an important element in the development of the organism. It is involved in the formation of various organs and tissues, such as skin, bones, muscles and blood vessels. It can also affect the growth and development of the body as a whole.
In general, somatic mesoderm plays an important role in the human and animal body. It provides communication between different layers of the skin, participates in the regulation of metabolism, and also affects the development and growth of the body.
Cells of mucoses and spermatogonia become keratinized along the periphery, forming a lamellar complex on the surface of the body, consisting of a layer of ciliary epithelial cells with inclusions of cytoplasmic granules and a layer of mesodermal cells. The body of many snails has areas of dopa-positive and cpa-negative integument.
