MEDICAL PHYSIOLOGY

Detailed explanation-1: -Your peripheral nervous system (PNS) is that part of your nervous system that lies outside your brain and spinal cord. It plays key role in both sending information from different areas of your body back to your brain, as well as carrying out commands from your brain to various parts of your body.

Detailed explanation-2: -The nervous system has two main parts: 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-3: -Broadly speaking, the nervous system is organised into two main parts, the central nervous system (CNS) and the peripheral nervous system (PNS). The CNS is the processing centre of the body and consists of the brain and the spinal cord. Both of these are protected by three layers of membranes known as meninges.

Detailed explanation-4: -Parts of the PNS. The PNS can be divided into two components: the somatic nervous system and the autonomic nervous system . The somatic nervous system (SNS) and the autonomic nervous system (ANS) are both parts of the peripheral nervous system.
