Any nerves and ganglia outside the brain and spinal cord come under the peripheral nervous system. The peripheral nervous system categorized into somatic and autonomic nervous system. The somatic part constitutes the sensory and motor neurons. Both cranial and spinal nerves are also part of the peripheral nervous system.
