Explanation / Answer

Answer

The rhythm of ventilation is determined by a group of neurons in the ventrolateral region of the Medulla Oblongata known as the rhythmicity center.

These neurons are arranged in 2 main groups; the Dorsal respiratory group that sends axons via the phrenic nerve to the diaphragm; and a Ventral group that contains both inspiratory and expiratory neurons.

The rhythmicity center is also influenced by the Pons which contains an Apneustic center that promotes inspiration; and a Pneumotaxic center that inhibits inspiration.
