Which functions are most likely to be at risk if the medulla is damaged?
Answer and explanation
Correct answer: Involuntary actions such as breathing and heartbeat
The medulla oblongata is part of the hindbrain and regulates several involuntary activities essential for survival, including breathing and heartbeat. Damage to it can therefore seriously disturb these automatic functions. The other options describe plant growth responses: phototropism, growth toward water, and pollen-tube guidance. They are controlled by plant tissues and chemical signals, not by the medulla of an animal nervous system.
