What is the peripheral nervous system comprised of?

The peripheral nervous system refers to parts of the nervous system outside the brain and spinal cord. It includes the cranial nerves, spinal nerves and their roots and branches, peripheral nerves, and neuromuscular junctions.

What are the 3 parts of the peripheral nervous system?

The peripheral nervous system is divided into the somatic nervous system, and the autonomic nervous system. The somatic nervous system is under voluntary control, and transmits signals from the brain to end organs such as muscles.

What nerves carry impulses from the PNS to the CNS?

The central nervous system consists of the brain and spinal cord. Cranial nerves, spinal nerves, and ganglia make up the peripheral nervous system. The afferent division of the peripheral nervous system carries impulses to the CNS; the efferent division carries impulses away from the CNS.

What is the parasympathetic system?

The parasympathetic nervous system is responsible for the body’s rest and digestion response when the body is relaxed, resting, or feeding.
