Detailed explanation-1: -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.
Detailed explanation-2: -More specifically, there are eight cervical nerve pairs (C1-C8), twelve thoracic nerve pairs (T1-T12), five lumbar nerve pairs (L1-L5), 5 sacral (S1-S5), and a single coccygeal nerve pair.
Detailed explanation-3: -The spinal cord is a bundle of nerves which extends from the brain down through most of the length of the spinal column, and pairs of nerves branch off roughly at each vertebra to supply nervous impulses for the body.
