Question

Respiration mechanism is controlled by

• A. Pons
• B. Medulla
• C. Limbic system
• D. Both A and B

Answer 1

Answer: (D)

Both A and B

The respiratory mechanism is controlled by two regions of the brainstem namely medulla oblongata and pons varolii. The medulla is the main region that regulates the muscles involved in contraction and allowing the mechanism of inhalation and exhalation. The pons is responsible for controlling the rate of breathing. The limbic system is the part of forebrain and is involved in memory, emotions, learning etc.

Hence, the correct answer is 'Both A and B'
