For the musician known as Somatic, see Hahn Rowe. The somatic nervous system (SoNS or voluntary nervous system) is the part of the peripheral nervous system associated with skeletal muscle voluntary control of body movements.The SoNS consists of afferent nerves and efferent nerves.esides these, thousands of association nerves are also present in the body. Thus somatic nervous system consists of three parts: 1  Spinal nerves: They are peripheral nerves that carry sensory information into and motor commands out of the spinal cord.
The muscular system primary job is to move the bones of the body not just that but muscle also makes the heart beat along with other organs. Muscle movement happens when signals produce electrical changes in muscle cells. They vary from the tiny muscles that move our eye balls in our sockets to the large muscle in our thighs. Opposing groups of muscles are muscles that contracts and relaxes at the same time such as straighten our knees. There are 3 types of muscle tissue: Skeletal muscle: this muscle creates movement in the body. There are more than 600 skeletal muscles, and they makes up about 40 percent of a personâs body weight. When the nervous system signals the muscle to contract, groups of muscles work together to move the skeleton.
