Although the ANS is also known as the visceral nervous system the ANS is only connected with the motor side. Most autonomous functions are involuntary but they can often work in conjunction with the somatic nervous system which provides voluntary control.
The somatic nervous system (SNS) is the portion of the nervous system responsible for voluntary body movement and for sensing external stimuli.All five senses are controlled by this system. The SNS is a sub-part of the peripheral nervous system.he somatic nerve system controls all five senses. Heat and pain are all transmitted by afferent neurons. The central nervous system consists of the brain and spinal cord. Afferent neurons carry impulses from sense organs to the brain, while efferent neurons carry impulses from the brain to the muscles.
