The pneumotaxic center normally inhibits the apneustic center and the inspiratory center to permit a normal rhythm of breathing.

Question

Quizplus · Accepted Answer

The pneumotaxic center, located in the pons of the brainstem, helps regulate the rate and depth of breathing by inhibiting the inspiratory center in the medulla oblongata and limiting the duration of inspiration, thereby preventing overinflation of the lungs. It does not directly inhibit the apneustic center, which helps prolong inspiration, but it can indirectly influence its activity by helping to regulate the length of the respiratory cycle. Overall, the pneumotaxic center helps maintain a normal respiratory rhythm by balancing the activity of the respiratory centers in the brainstem.
