Question

what is peripheral nervous system? ​

Answer 1

The peripheral nervous system (PNS) is one of two components that make up the nervous system of bilateral animals, with the other part being the central nervous system (CNS). The PNS consists of the nerves and gangliaoutside the brain and spinal cord.[1] The main function of the PNS is to connect the CNS to the limbs and organs, essentially serving as a relay between the brain and spinal cord and the rest of the body.[2] Unlike the CNS, the PNS is not protected by the vertebral columnand skull, or by the blood–brain barrier, which leaves it exposed to toxins and mechanical injuries.
