Why can damage to the medulla become a serious threat to life?
Answer and explanation
Correct answer: Because it controls involuntary actions like breathing and heartbeat
The medulla oblongata contains centres that regulate important involuntary activities, such as breathing, heartbeat and aspects of blood-vessel control. These functions continue without conscious effort and are essential for maintaining life. Serious damage may interrupt them and therefore become fatal. Hair colour, plant phototropism and taste are not the basis of this danger, so option A is correct.
