The Human Brain, Its Parts and Functions

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 ; Fore Brain Mid Brain Hind Brain

3. Fore Brain Position: It is the anterior part of the brain It has 3 parts Cerebrum Thalamus 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 Cerebellum Pons 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 Breathing Heart rate Swallowing Blood Circulation
