5. PARTS OF BRAIN
Human Brain is divided into 3 main parts on the basis of their
function and placements.
The 3 main parts of Human Brain are :-
1. Fore Brain
2. Mid Brain
3. Hind Brain

6. FORE BRAIN
Position :- It is the anterior part of the brain
It has 3 parts:-
1. Cerebrum
2. Thalamus
3. Limbic System

7. 1. CEREBRUM
Structure:- It is divided into 2 halves called Cerebral
Hemisphere.
•They communicate
via corpus collosum.
•Cerebral cortex is the
outer region of
Cerebrum.

8. FUNCTION OF CEREBRUM
 It helps In movement.
 It controls speech.
 It is responsible for sensory processing.
 It determines the intelligence of the being.

9. 2. THALAMUS
Position :- It is located
above the brain stem and
between the cerebral
cortex and mid-brain.
Function :- It carries
sensory information from
the body to Cerebrum
and The Limbic System.

10. HYPOTHALAMUS & PITUITARY
GLAND
HYPOTHALAMUS PITUITARY GLAND
Position: It lies under the
Thalamus.
Function: It connects
the nervous system
with the endocrine system
via pituitary gland.
Structure: It is peashaped
Structure.
Function: It is very
important in Growth and
reproduction.

11. 3. LIMBIC SYSTEM
Structure:- It is arc shaped structure between thalamus and
cerebrum.
Function:- It controls responses like
 Hunger
 Fear
 Thirst
 Anger
 Sexual responses, etc.

12. MID-BRAIN
Position:- It is located
below the cerebral
cortex and above the
hind brain.
Function:- It controls
reflex movements of
the body and hearing
Reflexes.

13. HIND-BRAIN
Position:- It is present at the
backside of the Brain.
Parts:- It consists of:-
1. Cerebellum
2. Pons
3. Medulla Oblongata

14. 1. CEREBELLUM
Meaning:- It is latin for Little Brain.
Position:- It is located at
the back side of head.
Functions:- It controls the
balance of the body and
co-ordinates the voluntary
movement of the body.

15. 2. Pons
Meaning:- Pons mean “Bridge”.
Position:- It is located above
medulla.
Function:- It controls sleep as
well as the rate and pattern of
breathing.

16. 3. Medulla Oblongata
Position:- It is the posterior part
of the brain.
Function:- It controls automatic
actions e.g.,
1. Breathing
2. Heart rate
3. Swallowing
4. Blood Circulation
