What is the name of the respiratory region found in the medulla oblongata and pons that is responsible for involuntary control of respiration?

Respiratory centers are clusters of neurons in the brainstem that generate and regulate the automatic breathing rhythm. In the medulla oblongata, the dorsal respiratory group drives inspiration, while the ventral respiratory group can contribute to expiration, especially during active or forceful breathing. The pons adds further modulation through the pneumotaxic and apneustic centers, which adjust the rate and depth of respiration to keep breathing smooth and coordinated. These centers receive chemical and mechanical feedback (like CO2 levels and lung stretch) and then send rhythmic signals to the respiratory muscles, maintaining involuntary control of breathing even without conscious input.
