Question

Match List I with List II

List I		List II
A	Pons	I	Provides additional space for Neurons, regulates posture and balance.
B	Hypothalamus	II	Controls respiration and gastric secretions.
C	Medulla	III	Connects different regions of the brain.
D	Cerebellum	IV	Neurosecretory cells

Choose the correct answer from the options given below:

• A. A-II, B-III, C-I, D-IV
• B. A-III, B-IV, C-II, D-I
• C. A-I, B-III, C-II, D-IV
• D. A-II, B-I, C-III, D-IV

Answer 1

The Correct Option is B

To match List I with List II, we should understand the functions of the brain regions listed in List I and connect them with the descriptions in List II. Here is the detailed explanation for each match:

List I	List II
A. Pons	III. Connects different regions of the brain.
B. Hypothalamus	IV. Neurosecretory cells
C. Medulla	II. Controls respiration and gastric secretions.
D. Cerebellum	I. Provides additional space for Neurons, regulates posture and balance.

Explanation:

• Pons - This part of the brainstem connects different regions of the brain, aiding in the relay of messages between them, thus matching with description III.
• Hypothalamus - Known for its role in homeostasis and controlling the endocrine system via neurosecretory cells, it corresponds to IV.
• Medulla - Responsible for autonomic functions like respiration and regulating gastric secretions, aligning with II.
• Cerebellum - Acts in motor control, posture, and balance, also known for housing a large number of neurons, so it fits with I.

Therefore, the correct matches are A-III, B-IV, C-II, D-I.

Answer 2

Matching Brain Structures with Their Functions:

A. Pons – Connects different regions of the brain and is associated with regulating respiration. 
Matches with: III. Connects different regions of the brain.

B. Hypothalamus – Contains neurosecretory cells, which control various hormonal functions. 
Matches with: IV. Neurosecretory cells.

C. Medulla – Controls respiration and gastric secretions. 
Matches with: II. Controls respiration and gastric secretions.

D. Cerebellum – Responsible for maintaining posture and balance. 
Matches with: I. Provides additional space for neurons, regulates posture and balance.

Thus, the correct answer is (2) A-III, B-IV, C-II, D-I.
