The peripheral nervous system is divided into the somatic nervous system and the autonomic nervous system. In the somatic nervous system, the cranial nerves are part of the PNS with the exception of the optic nerve (cranial nerve II), along with the retina.
What type of nerves are in the peripheral nervous system?
There are three types of peripheral nerves: motor, sensory and autonomic. Some neuropathies affect all three types of nerves, while others involve only one or two.

How CNS and PNS work together?
The PNS and CNS work together to send information between the brain and the rest of the body. Nerves emerge from the CNS through the skull and vertebral column, using the PNS to carry information to the rest of the body. The PNS is made up of two divisions – sensory and motor.
What is meaning of PNS?
The peripheral nervous system (PNS) is one of the two major divisions of the nervous system. … The nerves in the peripheral nervous system (PNS) connect the central nervous system (CNS) to sensory organs (such as the eye and ear), other organs of the body, muscles, blood vessels and glands.
