Answer 2

Question c(pontine respiratory group-switch between inspiration and expiration)

• These parts of the brainstem are correctly matched with their main function because it acts as on\off between the inspiration and expiration. It is also referred to as "pneumotaxic center".

• It is located in the medulla oblongata.

• Ventral respiratory groups- simulate the diaphragm contraction - The statement is not true as it helps in transferring impulses to Laryngeal and pharyngeal muscles. In simple words, it acts as a meditator.
• Dorsal respiratory groups-limit inflation of the lungs - The statement is not true as it helps the flow of breathing by triggering inspiratory impulses. In simple words, it acts as a mediator.
• All the above will be not taken into consideration as all the options are not correct.
