Detailed explanation-1: -The somatic nervous system is a component of the peripheral nervous system associated with the voluntary control of the body movements via the use of skeletal muscles.
Detailed explanation-2: -Somatic senses inform the nervous system about the external environment, but the response to that is through voluntary muscle movement. The term “voluntary” suggests that there is a conscious decision to make a movement. However, some aspects of the somatic system use voluntary muscles without conscious control.
Detailed explanation-3: -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.
Detailed explanation-4: -Skeletal muscle, attached to bones, is responsible for skeletal movements. The peripheral portion of the central nervous system (CNS) controls the skeletal muscles. Thus, these muscles are under conscious, or voluntary, control.
