When air enters the lungs, the lungs expand
Which of the following centers are responsible to
prevent the lungs from over- inflation?
Pulmonary stretch receptors present on the wall of bronchi and bronchioles of the airways respond to excessive stretching of the lung during large inspirations.
The amnestic center, which is located in the lower pons, is thought to excite the inspiratory center. Rather than abruptly sending signals to the inspiratory muscles to contract, stimulation of the apneustic center leads to a gradual increase in the firing rate of the inspiratory muscles.
The pneumotaxic center, located in the upper pons, sends inhibitory impulses to the inspiratory center, terminating inspiration, and thereby regulating inspiratory volume and respiratory rate.
The medulla oblongata is the primary respiratory control center. Its main function is to send signals to the muscles that control respiration to cause breathing to occur.
