CBSE Class 10 Science Exam 2020: Important Biology Diagrams with ...Brain ---Parts of brain and its functions

1Fore brain ---it consists of two parts cerebrum (large brain ) and olfactory lobe .
function :
(a)It is the site for all memory ,information processing ,calculation ,understanding etc. so we can say that this part ios mainly what makes us more intelligent and superior than other animals .

(b)This part of brain has specific regions which control all the sense organs like taste ,touch, sound vision and smell (olfactory lobe )

2 Mid brain -It connects the fore brain with hind brain.

3 Hind Brain ---It has three parts 
(1)cerebellum---It helps to maintain body balance  like cycling in straight line dancing with perfect movements .

It also helps in coordinating muscular movements like drawing painting and other skillful activities

(2)Pons -it is mainly responsible for breathing 

(3)Medulla oblongata--Also called brain stem .It controls all the involuntary actions eg heart beat,digestion excretion etc.it also controls reflex actions .

Spinal cord ----it is extension of brain and has several nerves emerging from it  and communicating with the body and outer world  .
The network of nerves that form a web all over the body and connect central nervous system to the ourter word is called peripheral nervous system.
How is brain protected -----
The delicate nervous  tissue present in brain is protected by a bony covering called skull and also inside brain there are layers called meninges which have fluid called cere brospinal fluid which acts as shock absorber and protects inner tissue from any jerk or shock.
