Question

Quizplus · Accepted Answer

The pacemaker activity that establishes the rhythmicity of breathing resides in the dorsal respiratory group (DRG). The DRG is a cluster of neurons located in the medulla oblongata, a part of the brainstem that controls basic physiological processes, including breathing. The DRG generates a rhythmic pattern of nerve impulses that controls the activity of the respiratory muscles involved in breathing.
