B
Medulla oblongata
C
Frontal lobe
D
Hippocampus
검증된 단계별 안내1
Understand the question: The problem asks which part of the brain controls involuntary functions like breathing, and how alcohol poisoning can suppress these functions.
Recall the function of each brain region mentioned: The cerebellum is responsible for motor coordination and balance, the frontal lobe is involved in decision-making and voluntary movement, and the hippocampus is key for memory formation. None of these are primarily responsible for involuntary functions like breathing.
Focus on the medulla oblongata: This part of the brainstem is responsible for regulating vital involuntary functions such as breathing, heart rate, and blood pressure. It plays a critical role in maintaining life-sustaining processes.
Connect the concept to alcohol poisoning: Alcohol poisoning can suppress the activity of the medulla oblongata, leading to dangerous consequences like slowed or stopped breathing, which can be life-threatening.
Conclude that the medulla oblongata is the correct answer based on its role in controlling involuntary functions and its vulnerability during alcohol poisoning.
