The muscular system is an organ system consisting of skeletal, smooth, and cardiac muscle. It permits movement of the body, maintains posture, and circulates blood throughout the body. [ 1 ] The muscular systems in vertebrates are controlled through the nervous system although some muscles (such as the cardiac muscle ) can be completely autonomous.
The functions of skeletal muscle include producing movement, maintaining body posture, controlling body temperature, and stabilizing joints. [8] Skeletal muscle is also an endocrine organ . [ 9 ] [ 10 ] [ 11 ] Under different physiological conditions, subsets of 654 different proteins as well as lipids, amino acids, metabolites and small RNAs ...

The human musculoskeletal system (also known as the human locomotor system, and previously the activity system) is an organ system that gives humans the ability to move using their muscular and skeletal systems. The musculoskeletal system provides form, support, stability, and movement to the body.

Striated or skeletal muscle only contracts voluntarily, upon the influence of the central nervous system. Reflexes are a form of non-conscious activation of skeletal muscles, but nonetheless arise through activation of the central nervous system, albeit not engaging cortical structures until after the contraction has occurred.

Myology is the study of the muscular system, including the study of the structure, function and diseases of muscle. [1] The muscular system consists of skeletal muscle, which contracts to move or position parts of the body (e.g., the bones that articulate at joints), smooth and cardiac muscle that propels, expels or controls the flow of fluids and contained substance.
The muscular system in vertebrates consists of three different types of muscles: cardiac, skeletal and smooth. Cardiac muscle is a striated muscle that makes up the heart. It is the only type of muscle consisting of branching fibers. Skeletal muscle consists of voluntary muscles attached to the frame of the skeletal system enabling bodily movement.
