If a person's breathing and heartbeat become abnormal but thinking ability remains normal which part is more suspicious?
Answer and explanation
Correct answer: Medulla
The symptoms point to a region that controls vital involuntary activities rather than conscious thought. The medulla, part of the brainstem, helps regulate breathing, heartbeat and other autonomic functions. Normal thinking suggests that the cerebrum, which supports higher mental activity, may be functioning comparatively normally. Therefore option A is the best conclusion. The tongue is an organ involved in taste and movement, and the pancreas regulates digestive enzymes and hormones, not the primary control of breathing and heartbeat.
