PATHOLOGY

Detailed explanation-1: -The primary function of the peripheral system is to assist the brain and spinal cord to receive and send information from and to all parts of the body. The peripheral nervous system consists of 12 pairs of cranial nerves and 31 pairs of spinal nerves.

Detailed explanation-2: -Cranial nerves emerge from the cranium (brain/brainstem) whilst spinal nerves leave the CNS via the spinal cord. There are 12 pairs of cranial nerves and 31 spinal nerve pairs, giving a total of 43 paired nerves forming the basis of the peripheral nervous system.

Detailed explanation-3: -Cranial nerves: There are 12 pairs of nerves that connect directly to your brain, and 11 of them are part of your peripheral nervous system (the second cranial nerve, which controls your vision, is part of your central nervous system).

Detailed explanation-4: -Peripheral nervous system is divided into somatic and autonomic nervous systems. Somatic nervous system consists of cranial nerves and spinal nerves. There are 12 pairs of cranial nerves in the brain connecting head and upper body, while 31 pairs of spinal nerves connecting the rest of the body.
