Where is the respiratory center located in the brain?

• A. Cerebellum
• B. Cerebrum
• C. Medulla and pons
• D. Diencephalon

Answer: (C)

Breathing is controlled by centers in the brainstem, not by higher brain regions. The respiratory center lies in the medulla oblongata and the adjacent pons. In the medulla, the dorsal respiratory group handles routine inspiratory pacing, while the ventral respiratory group activates expiration during higher demand; the pons modulates the transition between inhalation and exhalation to smooth the rhythm. The cerebellum coordinates movement, the cerebrum handles conscious control, and the diencephalon mainly processes relay and autonomic input, not the primary rhythm. So the location is the medulla and pons.
