With respect to the control of ventilation,which brain region stimulates the internal intercostal muscles to contract,causing forced exhalation?
A)Dorsal respiratory group (DRG)
B)Ventral respiratory group (VRG)
C)Apneustic area
D)Pneumotaxic area
E)Pleurotaxic area

Question

Quizplus · Accepted Answer

The ventral respiratory group (VRG) is responsible for controlling the muscles of forced exhalation, including the internal intercostal muscles. The dorsal respiratory group (DRG) is responsible for controlling the muscles of inhalation, while the apneustic and pneumotaxic areas are involved in controlling the rhythm and depth of breathing. The pleurotaxic area is not a recognized brain region involved in the control of ventilation.
