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

PARTS OF BRAIN Human Brain is divided into 3 main
parts on the basis of their function and placementsThe 3 main parts of Human Brain are ;
1. Fore Brain 2. Mid Brain3. Hind Brain

FORE BRAIN Position: It is the anterior part of the
brain
It has 3 parts 1. Cerebrum 2. Thalamus 3. Limbic System
![Page 4: The Human Brain, Its Parts and Functions](https://reader036.fdocuments.in/reader036/viewer/2022062503/589e6c741a28ab1a548b689f/html5/thumbnails/4.jpg)
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
![Page 5: The Human Brain, Its Parts and Functions](https://reader036.fdocuments.in/reader036/viewer/2022062503/589e6c741a28ab1a548b689f/html5/thumbnails/5.jpg)
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
![Page 6: The Human Brain, Its Parts and Functions](https://reader036.fdocuments.in/reader036/viewer/2022062503/589e6c741a28ab1a548b689f/html5/thumbnails/6.jpg)
LIMBIC SYSTEM
Structure: It is arc shaped structure between thalamus and cerebrum
Function: It controls responses like Hunger Fear Thirst Anger Sexual responses etc
![Page 7: The Human Brain, Its Parts and Functions](https://reader036.fdocuments.in/reader036/viewer/2022062503/589e6c741a28ab1a548b689f/html5/thumbnails/7.jpg)
CEREBRUM Structure: It is divided into 2 halves called cerebral
hemisphere
They communicate via corpus collosum
Cerebral cortex is the outer region of Cerebrum
![Page 8: The Human Brain, Its Parts and Functions](https://reader036.fdocuments.in/reader036/viewer/2022062503/589e6c741a28ab1a548b689f/html5/thumbnails/8.jpg)
FUNCTION OF CEREBRUM
It helps In movement It controls speech It is responsible for sensory processing It determines the intelligence of the
being
![Page 9: The Human Brain, Its Parts and Functions](https://reader036.fdocuments.in/reader036/viewer/2022062503/589e6c741a28ab1a548b689f/html5/thumbnails/9.jpg)
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
![Page 10: The Human Brain, Its Parts and Functions](https://reader036.fdocuments.in/reader036/viewer/2022062503/589e6c741a28ab1a548b689f/html5/thumbnails/10.jpg)
HIND-BRAINPosition: It is present at
the backside of the Brain
Parts: It consists of 1. Cerebellum 2. Pons 3. Medulla Oblongata
![Page 11: The Human Brain, Its Parts and Functions](https://reader036.fdocuments.in/reader036/viewer/2022062503/589e6c741a28ab1a548b689f/html5/thumbnails/11.jpg)
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
![Page 12: The Human Brain, Its Parts and Functions](https://reader036.fdocuments.in/reader036/viewer/2022062503/589e6c741a28ab1a548b689f/html5/thumbnails/12.jpg)
PONS Meaning: Pons mean
“Bridge”
Position: It is located above medulla
Function: It controls sleep as well as the rate and pattern of breathing
![Page 13: The Human Brain, Its Parts and Functions](https://reader036.fdocuments.in/reader036/viewer/2022062503/589e6c741a28ab1a548b689f/html5/thumbnails/13.jpg)
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
