Summary Introduction
Introduction:
Nervous system is the hub where all the processing of the messages coming from different parts of the body. It comprises two sections in vertebrates, namely central and peripheral nervous system. The central part comprises of the brain and the spinal cord, while the peripheral section mainly comprises the nerves.
