Quizplus · Accepted Answer

The reticular activating system is responsible for screening incoming information and arousing higher centers in response to important stimuli such as the sound of her toddler and his cry for attention. The medulla controls basic life-sustaining functions such as breathing and heart rate, while the pons helps control sleep and arousal. The cerebellum is responsible for motor coordination and balance, which are not relevant to this scenario.
