MICROANATOMY

Detailed explanation-1: -The peripheral nervous system refers to parts of the nervous system outside the brain and spinal cord. It includes the cranial nerves, spinal nerves and their roots and branches, peripheral nerves, and neuromuscular junctions.

Detailed explanation-2: -The cranial nerves are considered components of the peripheral nervous system (PNS), although on a structural level the olfactory, optic and terminal nerves are more accurately considered part of the central nervous system (CNS).

Detailed explanation-3: -Our nervous system is divided in two components: the central nervous system (CNS), which includes the brain and spinal cord, and the peripheral nervous system (PNS), which encompasses nerves outside the brain and spinal cord.

Detailed explanation-4: -The central nervous system is made up of the brain and spinal cord. The peripheral nervous system is made up of nerves that branch off from the spinal cord and extend to all parts of the body.

Detailed explanation-5: -The spinal nerves and the cranial nerves make up the peripheral nervous system (PNS). These nerves are the passages by which information travels to and from the central nervous system (CNS) and the rest of the body. There are 31 pairs of spinal nerves and 12 pairs of cranial nerves.
