Answer:
This is the Ventral Regulatory Group-VRG
Explanation:
In the medulla,there are four groups of neurons which forms the exhalation parts of the respiratory control.These 4 groups are called the VRG.They occupy 5mm anterior in length, and laterally positioned to the dorsal respiratory group.They are therefore said to occupy the ventrolateral part of the medulla.
The dorsal respiratory group(DRG) consists of the inspiration neurons,contrary to the VRG. They do not extend to the DRG,but the DRG, extends to them
They(VRG) function in propagating action potentials needed for the mechanisms of respiration.(exhalations), and Inspirations
