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
