Myotome

The myotome is part of the somite, which is the region of mesoderm from which all skeletal and smooth muscles develop. It is formed at an early stage of embryonic development and plays an important role in the formation of the muscular system.

The myotome consists of two layers of cells called epiboly and entoboly. The epiboly is the outer layer and the entoboly is inside the myotome. Epiboly cells form epithelial tissue that covers the inner surface of the myotome. Entoboly consists of muscle cells that begin to develop from myotome mesodermal material.

Smooth muscle development also originates from the mesoderm. They are formed from segmented mesoderm and develop mainly in the walls of blood vessels and internal organs. Smooth muscles do not have a skeletal structure, but they are also necessary for coordinating movements and regulating body functions.

In general, the myotome plays a key role in the development of the muscular system, providing the necessary material for the formation of skeletal and smooth muscles.

The myotome is part of the somite, an area of ​​mesoderm that turns into skeletal muscle and smooth muscle early in embryonic development. The myotome is one of the main elements that determine the shape and structure of the body in animals.

The myotome develops from the somite, a segment of mesoderm that forms at the blastula stage. During embryonic development, the somite is divided into several parts called myotomes. Each myotome forms its own group of muscles, which will subsequently develop into different groups of skeletal muscles.

Smooth muscle development also originates from the mesoderm. However, unlike skeletal muscles, smooth muscles do not have a bony structure and are not part of the skeleton. Smooth muscles are located in the walls of blood vessels, intestines, respiratory tracts and other organs.

Thus, the myotome plays an important role in the formation of the body in animals, as it determines the structure and shape of skeletal and smooth muscles. Knowledge of myotomes can help in understanding muscle development and their role in the body.

The myotome is part of the somite - a section of mesoderm at an early stage of embryonic development, which in the future develops into all skeletal muscle tissues. At this time, the embryo, which is in the ninth week of intrauterine development, begins the formation of skeletal muscles and the circulatory system. The main task of myot is to create the necessary conditions for the formation of skeletal tissues: muscles, fascia and tendons, as well as blood vessels. Its development is under the control of genetic and biochemical factors.

Smooth muscle tissues develop from non-stratified mesoderm, which means they contain segmented cells. These types of muscle fibers require a lot of oxygen and nutrients, and therefore their growth is quite slow, which explains the smaller number of fast-acting skeletal muscles compared to other structures of the body.
