Somatic afferent nerves
The somatic nervous system (SNS), or voluntary nervous system is the part of the peripheral nervous system associated with the voluntary control of body movements via skeletal muscles. The somatic nervous system consists of sensory nerves carrying afferent nerve fibers, which relay sensation from the body to the central nervous system (CNS), and motor nerves carrying efferent nerve fibers, which relay motor commands from the CNS to stimulate muscle contraction.
