+4 / -1
The respiratory centre that controls normal breathing rhythm is located in the:
A
Cerebral cortex
B
Cerebellum
C
Medulla oblongata
D
Hypothalamus
Explanation
The medulla oblongata (part of the brainstem) contains the primary respiratory rhythm centre (dorsal and ventral respiratory groups) that generates the basic breathing pattern. The pneumotaxic and apneustic centres in the pons modulate this rhythm. Voluntary control of breathing is possible through the cerebral cortex (e.g., during speaking or breath-holding).
