the human brain, its parts and functions
TRANSCRIPT
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
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
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
LIMBIC SYSTEM
Structure: It is arc shaped structure between thalamus and cerebrum
Function: It controls responses like Hunger Fear Thirst Anger Sexual responses etc
CEREBRUM Structure: It is divided into 2 halves called cerebral
hemisphere
They communicate via corpus collosum
Cerebral cortex is the outer region of Cerebrum
FUNCTION OF CEREBRUM
It helps In movement It controls speech It is responsible for sensory processing It determines the intelligence of the
being
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
HIND-BRAINPosition: It is present at
the backside of the Brain
Parts: It consists of 1. Cerebellum 2. Pons 3. Medulla Oblongata
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
PONS Meaning: Pons mean
“Bridge”
Position: It is located above medulla
Function: It controls sleep as well as the rate and pattern of breathing
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
