Nervous System


The human nervous system consists of two parts

The central nervous system is the main control centers like the brain and the

spinal chord.

 

The peripheral nervous system consists of nerves, which reach the rest of the

body which is also known as the periphery.

 

Nerve cell

Nerve cells can also be called neurons and carry messages known as impulses.

Nerves carry the impulse through the body and then the nerve is sent to the

rest of the body through the dendrites which have many other nerves

attached to it.

 

There are two types of neurons sensory and motor neurons Sensory neurons

are involved in relaying the impulses from the point of impact or otherwise

known as the receptors to the central nervous system.

 

The central nervous system then decides what action to take, and it then send

another set of impulses through a set of motor neurons to the effector.
