In which situation can disturbance of the medulla be most dangerous?
Answer and explanation
Correct answer: Disturbed control of breathing and heartbeat
The medulla contains centres that help regulate vital involuntary activities, including breathing and heartbeat. These functions continue without conscious control and are essential for maintaining life. Therefore damage or disturbance to the medulla can seriously disrupt both and may be life-threatening, making option B correct. Drawing is a higher cerebral function, while the plant responses in options C and D are controlled by plant growth mechanisms, not the medulla.
