The central nervous system (CNS) is the part of the nervous system consisting of the brain and spinal cord.
The peripheral nervous system is divided into the somatic nervous system and the autonomic nervous system; some textbooks also include sensory systems.The cranial nerves are part of the PNS with the exception of cranial nerve II, the optic nerve, along with the retina.he second cranial nerve is not a true peripheral nerve but a tract of the diencephalon. Cranial nerve ganglia originate in the CNS. However, the remaining twelve cranial nerve axons extend beyond the brain and are therefore considered part of the PNS.
