Nervous System
The nervous system is made up
of brain, spinal cord and
nerves.
The brain is an important organ of our body. It is 
the control centre of our body. It sends and 
receives messages from different parts of the 
body through spinal cord and nerves. It is protected 
by the bony skull. The space between the brain and 
the skull is filled with a fluid that acts as a shock  absorber. This 
fluid protects the brain from injuries.

The brain has three main parts:
1) Cerebrum                                        2) Cerebellum                                  3) Medulla oblongata.
It is the largest part
of the human brain.
It has many grooves
and folds. It is the
centre of
intelligence. It
controls our sense
organs. It is
responsible for
thinking, learning
and reasoning.
It lies below the cerebrum. It controls
and coordinates the movement of
muscles. It also helps in maintaining
the balance of our body.
It is also called the
brain stem. It lies at
the base of the
brain. It connects
the brain to the
spinal cord. It
controls
involuntary actions
like breathing,
digestion,
swallowing and
heartbeat.
