Brain:-structure and function

Structure and Function of brain and its different parts

1. THE BRAIN :- STRUCTURE and it’s FUNCTIONS Submitted By:- Suyash Jain B Pharm (1 st sem ) Department of Pharmaceutical Sciences Dr. Hari Singh Gour University Sagar(M.P.)

2. THE BRAIN

3. 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

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

5. 1. CEREBRUM Structure :- It is divided into 2 halves called Cerebral Hemisphere . They communicate via corpus collosum . Cerebral cortex is the outer region of Cerebrum.

6. FUNCTION OF CEREBRUM It helps In movement. It controls speech. It is responsible for sensory processing. It determines the intelligence of the being.

7. 2. 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.

8. HYPOTHALAMUS & PITUITARY GLAND HYPOTHALAMUS PITUITARY GLAND Position : It lies under the Thalamus. Function : It connects the nervous system with the endocrine system via pituitary gland. Structure: It is peashaped Structure. Function : It is very important in Growth and reproduction.

9. 3. LIMBIC SYSTEM Structure :- It is arc shaped structure between thalamus and cerebrum. Function:- It controls responses like Hunger Fear Thirst Anger Sexual responses, etc.

10. 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.

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

12. 1. 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.

13. 2. Pons Meaning:- Pons mean “Bridge”. Position:- It is located above medulla. Function:- It controls sleep as well as the rate and pattern of breathing.

14. 3. Medulla Oblongata Positi on:- 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
