AIIMS 2019 Zoology Neural Regulation of Respiration Assertion Reason Question
Assertion: Pneumotaxiccentre is situated in Pons Reason: It can regulate the functioning of rhythm centre.
Both assertion and reason are true, and reason is the correct explanation of assertion.
Both assertion and reason are true, but reason is not the correct explanation of assertion.
Assertion is true, but reason is false.
Both assertion and reason are false.
Correct Answer
Detailed Explanation
Option B is correct because both the assertion that the pneumotaxic center is located in the pons and the reason that it regulates the functioning of the rhythm center are true; however, the reason does not directly explain why the assertion is correct. The pneumotaxic center primarily modulates the rate and pattern of breathing, but it does not serve as the sole explanation for its anatomical location.
Option A is incorrect because, while both statements are true, the reason fails to clarify the assertion. Option C is incorrect as both statements are true, and option D is incorrect since both the assertion and reason are factual. Understanding the roles of the pneumotaxic center and the rhythm center in respiratory physiology is essential for grasping their interrelated functions.
