Detailed explanation-1: -The somatic nervous system provides control of skeletal muscle movement. Conscious control of movement originates in the motor cortex (both premotor and primary motor cortex). However, movement is refined and coordinated by various structures in the CNS, including extrapyramidal regions and the cerebellum.
Detailed explanation-2: -The somatic nervous system, also called the somatomotor or somatic efferent nervous system, supplies motor impulses to the skeletal muscles. Because these nerves permit conscious control of the skeletal muscles, it is sometimes called the voluntary nervous system.
Detailed explanation-3: -The somatic nervous system controls voluntary movements, transmits and receives messages from the senses, and is involved in reflex actions without the involvement of the CNS so that the reflex can occur very quickly.
