Central Nervous System Respiratory Center (CNS Respiratory Center)

The central nervous system (CNS) respiratory center is a network of interconnected neuronal groups located primarily in the brainstem—specifically, the medulla oblongata and pons. This center is responsible for generating and maintaining the rhythm of breathing, as well as adjusting respiratory patterns in response to physiological changes such as altered levels of oxygen (O₂), carbon dioxide (CO₂), and blood pH. Key subregions include the Dorsal Respiratory Group (DRG), Ventral Respiratory Group (VRG), Pneumotaxic Center, and Apneustic Center.
