twelve pairs of cranial nerves and 31 pairs of pairs of spinal nerves with their ganglia make up the ____
A
central nervous system
B
peripheral nervous system
C
spinal cord
D
cauda equina
Explanation: 

Detailed explanation-1: -Thirty one pairs of spinal nerves exist: 8 cervical, 12 thoracic, 5 lumbar, 5 sacral, and 1 coccygeal. Proximal branches: Each spinal nerve branches into a posterior root and an anterior root. The spinal or posterior root ganglion is occupied by cell bodies from afferent neurons.

Detailed explanation-2: -The Sensory-Somatic Nervous System. The sensory-somatic system consists of 12 pairs of cranial nerves and 31 pairs of spinal nerves.

Detailed explanation-3: -In total, there are 31 pairs of spinal nerves grouped regionally by spinal region. 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-4: -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.
