Question

Quizplus · Accepted Answer

The ventral respiratory centers in the medulla oblongata send motor signals during inspiration to the diaphragm, larynx, and pharynx. Therefore, choice A, which includes all three structures, is the best answer. The sternocleidomastoids are involved in forced inspiration, so they are not typically activated during quiet breathing.
