PART 1INTRODUCTION TO THE NERVOUS SYSTEM The survival of organisms depends on their ability to sense and respond to things around them. Sense organs of the body such as the eyes take in information from an organism’s surroundings and send them to the brain. The cells that make up the nervous system are called nerve cells or
The human nervous system is a communication network of neurons nerve cells which serve to conduct a variety of messages to and from various parts of the body. There are two distinct types of nerve tissues neurons which are the basic structural units of the nervous system and neuroglia which act as supporting nerve tissue for the neurons.
The central nervous system coordinates the functioning of all parts of the human body and is the largest part of the nervous system. It is enveloped by a set of membranes known as meninges that protect the brain and the spinal cord.
