which part of the nervous system consists of all of the spinal nerves and cranial nerves
Depending on the originating place (either brain or spinal cord), peripheral nervous system can be classified into two categories; namely, cranial nerves and spinal nerves. Along these two types of nerves that arise from brain and spinal cord, central nerve system communicates with the rest of the body.
The Peripheral Nervous System. The peripheral nervous system consists of the nerves that branch out from the brain and spinal cord. These nerves form the communication network between the CNS and the body parts. The peripheral nervous system is further subdivided into the somatic nervous system and the autonomic nervous system. The somatic nervous system consists of nerves that go to the skin and muscles and is involved in conscious activities.
