Abstract: Skeletal muscle is the largest tissue in mammals, and the loss of its functional or regenerative properties could lead to dysplasia and muscle skeletal diseases. The animal body has more than 600 muscles, which play a role in support and exercise. Skeletal muscle can be autonomously controlled by the body, which is a feature different from smooth muscle and cardiac muscle. The skeletal muscle of agricultural animals is the main source of meat products, providing humans with high-quality animal protein and nutrients. There are many factors that affect growth and development. The growth and development of muscle determines the yield and quality of pork, which arecrucial economic characters in agricultural animal production. The regulation of growth and development of skeletal muscle involves the activation or silencing of many genes and related pathways, which is a complex multi-level regulatory network. Here, the structure and composition, and growth and development process of skeleta muscle are reviewed. This paper also introduces many regulators on muscle development, including growth factors and cytokines. Base on the available results, it is believed that the future research will focus on the experimental validation of important candidate genes in vitro and in vivo, and then finally applytobreeding practice, which will provide a theoretical foundation for the study on molecular regulation mechanism of growth and development of skeletal muscle and the treatment of muscle genetic diseases.

Key words: skeletal muscle; growth and development; regulation
