Where Is the Somatic Nervous System Located?

The somatic nervous system consists of the cell bodies located in either the brainstem or the spinal cord. They have an extremely long course as they do not synapse after they leave the CNS until they are at their termination in skeletal muscle. They consist of large diameter fibers and are ensheathed with myelin.

Where is the somatic nervous system?

The somatic peripheral nervous system is a single neuron system with the motor neurons lying inside the brainstem or spinal cord and the sensory neurons lying in the dorsal root ganglia. The autonomic peripheral nervous system is a two neuron system with a neuron lying outside of the CNS in the autonomic ganglia.

What is part of the somatic nervous system?

The somatic nervous system consists of sensory nerves carrying afferent nerve fibers that relay sensation from the body to the central nervous system (CNS). The other nerves in the SNS are motor nerves carrying efferent nerve fibers that relay motor commands from the CNS to stimulate muscle contraction.
