Somatic nervous system

The somatic nervous system (SNS) is part of the peripheral nervous system.Dorlands Medical Dictionary: somatic nervous system It controls various muscles and the sensory input from external stimuli 

The SNS controls voluntary body movements by skeletal muscles. Its outgoing (efferent) nerves stimulate muscle contraction. Its incoming (afferent) nerves relay sensation from the skin, and sense organs to the central nervous system. This includes touch, hearing, and sight.

The SNS does not, however, control reflex arcs.
