Is the spinal cord considered part of the peripheral nervous system?

Correct answer is NO. The spinal cord is not considered part of the peripheral nervous system (PNS). The spinal cord is a vital component of the central nervous system (CNS), along with the brain. The PNS, on the other hand, consists of nerves and ganglia outside the brain and spinal cord. It includes sensory and motor neurons that connect the CNS to the rest of the body, facilitating communication between the central and peripheral parts of the nervous system.
