Question

Describe the structure and function of the human brain in brief.

Hint:

Remember the three parts of the brain — Cerebrum (thinking), Cerebellum (balance), and Medulla (involuntary actions).

Answer 1

Step 1: Structure of the Human Brain.
The human brain is divided into three main parts:
1. Cerebrum:
- The largest part of the brain.
- Responsible for intelligence, memory, learning, emotions, and voluntary actions.
- It is divided into two hemispheres (right and left) that control opposite sides of the body.
2. Cerebellum:
- Located below the cerebrum at the back of the skull.
- Controls balance, posture, and coordination of muscles.
- Ensures smooth and precise body movements.
3. Medulla Oblongata (Brain Stem):
- Found below the cerebellum, connecting the brain to the spinal cord.
- Controls involuntary activities such as heartbeat, breathing, digestion, and blood pressure.
Step 2: Diagram Description (for Overleaf).
A labeled diagram shows:
- Cerebrum (top large part)
- Cerebellum (below cerebrum, small oval shape)
- Medulla oblongata (stem-like lower part connecting to the spinal cord).
Step 3: Function Summary.
The brain coordinates all activities of the body — voluntary and involuntary — and is responsible for maintaining homeostasis, thinking, and body control.
Step 4: Conclusion.
Thus, the human brain is a complex organ that acts as the command center of the nervous system, regulating thoughts, emotions, and vital functions.
