functioning as the coordinating centre of the body

3. 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

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

5. CEREBRUM
Structure:
It is divided into 2 halves called cerebral
hemisphere
They communicate
via corpus collosum
Cerebral cortex is
the outer region
of Cerebrum

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

7. 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

8. HYPOTHALAMUS
Position: It lies under the
thalamus
Function: It connects the
nervous system with the
endocrine system via pituitary
gland
HYPOTHALAMUS & PITUITARY
GLAND
PITUITARY
GLAND
Structure: It is pea-shaped
structure
Function: It is very
important
in Growth and reproduction

9. LIMBIC SYSTEM
Structure: It is arc shaped structure between
thalamus and cerebrum
Function: It controls responses lilllll
 Fear
 Thirst

 Sexual responses etc

10. MID-BRAIN
Position: It is located lbelow the cerebral cortex and
above the hind brain
Function: It controls reflex
Movements of the body & hearing
Reflexes.

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

12. PONS
Meaning: Pons( Bridge)
Position: It is located
above medulla
Function: It controls sleep as
well as the rate and pattern of
breathing

13. MEDULLA OBLONGATA
Position: It is the posterior part of
the brain

actions e.g
1. Breathing
2. Heart rate
3. Swallowing
4. Blood Circulation

14. CEREBELLUM

at the back side of head
Functions: It controls
