Quick Summary

General somatic efferent fibers are a type of nerve fiber that carries motor information from the central nervous system to skeletal muscles in the body wall and extremities. These fibers originate from large ventral-horn cells within the spinal cord. Nerves are bundles of fibers that connect the nervous system to other body parts, conducting impulses. Spinal nerves, which are attached to the spinal cord, are considered mixed nerves because they contain both sensory and motor fibers. The somatic efferent fibers specifically innervate voluntary muscles that develop from embryonic myotomes.12
