Biology:-Nervous system
Every thing is known by the brain without that you cannot do any thing.nervous system is made of brain,spinal cord,nerves.brain is jelly substance and it is 1.5 kilos or 3pounds.brain communicate with the help of spinal cord and nerves.it tells what is going every time.and also gives instructions what to do.brain is made of millions of nerve cells.brain is divided into 2 parts by ours they are right and left brain.right side controll left and opposit.parts of the brain.cerebrum,cerebellum,thalamus,brain stem.
