Prolonged Inspirations Can Result from Stimulating the ________ Center

Question

Prolonged inspirations can result from stimulating the ________ center.
A) apneustic
B) pneumotaxic
C) expiratory
D) baroreceptor
E) chemoreceptor

Accepted Answer

Prolonged inspirations are controlled by the respiratory centers in the brainstem, including the apneustic center and the pneumotaxic center. Stimulation of the apneustic center results in prolonged inspirations, hence A is the correct answer. The pneumotaxic center, on the other hand, helps to regulate the duration of each breath. The expiratory center controls expiration, while the baroreceptor and chemoreceptor centers are involved in the regulation of blood pressure and blood gas levels, respectively.
