Nervous tissues are made of a neuron. Some neuron carries impulses from tissues to the brain and some carry impulses from the brain to the tissues. Nervous system is divided into 3 main parts, they are:
It is also divided into two main parts, they are:
The brain is the main part of the central nervous system which is safely enclosed in the skull. The brain sends the message to organs and tissues and receives impulses from them. It consists of different parts, they are:
The spinal cord is the next organ of the central nervous system. It lies inside the vertebral Column. There are 31 pairs of spinal nerves coming out from the spinal cord and they are spread to different part of our body. It is the main center for reflex action.
Its functions are:
There are 12 pairs of nerves coming out from the brain and 31 pairs of nerves are coming out from spinal cord function under a peripheral nervous system.
