II.pneumotaxic center
III.pulmonary stretch receptors

Question

Quizplus · Accepted Answer

The inhibitory neurons that switch off the inspiratory ramp signal are controlled by the pneumotaxic center and pulmonary stretch receptors. The pneumotaxic center modulates the switch-off point of the inspiratory neurons, thus controlling the rate and pattern of breathing. Pulmonary stretch receptors, activated during lung inflation, also contribute to the termination of inspiration through the Hering-Breuer reflex. The apneustic center, on the other hand, promotes inspiration and is not directly involved in switching off the inspiratory ramp signal.
