The Human Brain, Its Parts and Functions

1. HUMAN BRAIN
 Brain is organ of soft nervous tissue
contained in the skull of vertebrates,
functioning as the coordinating centre of the
body

2. 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

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

4. 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

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

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

7. 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. 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

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

11. 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

12. PONS
 Meaning: Pons mean
“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
 Function: It controls
automatic actions e.g
1. Breathing
2. Heart rate
3. Swallowing
4. Blood Circulation

14. A SMALL CLIP 
