Question

Quizplus · Accepted Answer

Inspiratory and expiratory neurons are located in the respiratory control center in the brain stem, which controls the rate and depth of breathing. These neurons respond to signals that arise from the body's need for more or less oxygen or to remove excess carbon dioxide. They are not located in the breathing tubes and are not primarily sensitive to PO₂.
