Inspiration occurs when the vagus nerve stimulates the diaphragm to contract.

Question

Quizplus · Accepted Answer

Inspiration occurs when the diaphragm contracts and the chest wall expands, resulting in a decrease in pressure within the lungs which causes air to rush in. The vagus nerve is responsible for regulating the function of several organs, including the heart and lungs, but it does not directly trigger diaphragmatic contraction during inspiration.
