Nervous system(CNS) Is the chief controlling & co-ordinating system of the body. It controls the voluntary & involuntary activities of the body & adjust the individual to given surroundings. Nerves are the protoplasmic extension of the nerve(neuron) form the neural pathways called the nerves. Impulses are given out to brain & goes out the whole body is called as efferent pathway & impulses going from body to brain are the afferent pathway.
