Question

Human brain has various parts or regions that help in different actions, responses and coordination. From the following, identify the part responsible for precision of voluntary actions :

• A. Cerebrum
• B. Cerebellum
• C. Medulla
• D. Pons

Hint:

If the question asks for "thinking" or "reasoning," choose Cerebrum. If it asks for "balance" or "precision," choose Cerebellum.

Answer 1

The Correct Option is B

Step 1: Understanding the Concept:
The human brain is divided into the forebrain, midbrain, and hindbrain.
Voluntary actions are initiated by the forebrain, but their "finesse" and "coordination" are managed by the hindbrain.
Step 2: Detailed Explanation:
1. Cerebrum: Responsible for intelligence, memory, and initiating voluntary movements.
2. Cerebellum: Located in the hindbrain; it coordinates muscular activity and maintains body posture and balance. It is specifically responsible for the precision of voluntary actions like walking in a straight line or picking up a pencil.
3. Medulla: Controls involuntary actions like blood pressure and salivation.
4. Pons: Involved in regulating respiration.
Step 3: Final Answer:
The cerebellum is responsible for the precision and coordination of voluntary actions.
