Question

What is the full form of CNS?

Answer 1

Hint: The CNS is made up of the brain and spinal cord. It is the most important organ of our body which controls the functions of our body and mind. The CNS helps our body to respond to stimuli.

Complete Answer: -
The Nervous system of our body is the most important system which comprises the brain, spinal cord, nerves etc. It coordinates the functions, behaviour and also transmits signals to various parts of the body. The nervous system is divided into two parts-
CNS or central nervous system- It comprises the brain and spinal cord. The brain acts like a computer which controls all the functions of our body. The brain is the centre of thoughts, intelligence, and memory. It processes the information received by the nerves. The spinal cord is an important organ which is the centre for interpreting the stimuli received and directs the motor nerves for providing suitable responses.

PNS or peripheral nervous system- They are the series of nerves which branch out from the brain and the spinal cord. The sensory nerves are the nerves which bring the information/stimuli to the brain or spinal cord for processing. The motor nerves carry the processed information to the effector organs.

Hence, the full form of CNS is the central nervous system.

Note:
The nervous system is made up of several million neurons. The neurons are the structural and functional unit of the nervous system. They are capable of carrying information. These neurons are present all over the body and are capable of quick signalling.
