Somatic nervous system

From Simple English Wikipedia, the free encyclopedia

The somatic nervous system (SNS) is part of the peripheral nervous system.[1] 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.
