Quizplus · Accepted Answer

The phrenic nerve controls the diaphragm, which is the major muscle involved in inspiratory activity. The vagus nerve controls the parasympathetic activity of the heart, lungs, and digestive tract. The intercostal nerves control the muscles between the ribs, which are involved in breathing, but not the major muscle for inspiration. "Brain stem nerve" and "pace maker nerve" are not specific enough terms to accurately describe the nerve controlling inspiratory activity.
