Why is the medulla linked with life-supporting functions?
Answer and explanation
Correct answer: Because it controls involuntary actions like breathing and heartbeat
The governing concept is involuntary control by the hindbrain. The medulla oblongata contains centres that regulate vital automatic activities such as breathing, heartbeat and blood-vessel actions. These processes continue without conscious decision and are essential for survival, which explains the term life-supporting functions. Memory, taste perception and formation of a hand bone are not the principal roles of the medulla.
