Overview

The nervous system consists of all of the nerve cells in the human body. It is responsible for signal transmission between the brain and other organs of the body. It receives information from the senses, interprets it and sets off reactions, such as muscle contraction or feeling pain. The peripheral nervous system (PNS) and the central nervous system (CNS) are the two major components of the nervous system. The CNS is made up of the spinal cord and the brain, while PNS is primarily made up of nerves which are bundles of axons or fibers that link the CNS to every other organ and tissue in the body. The nervous system also comprises glia, which are non-neuron cells and perform significant functions to make the nervous system function properly. This book outlines the molecular mechanisms in the nervous system in detail. Its extensive content provides the readers with a thorough understanding of the subject.
