Question

The brain stem is critical to survival because it:

a) Controls higher cognitive functions
b) Regulates emotions and social behavior
c) Manages complex motor movements
d) Controls basic life-sustaining functions like breathing and heart rate

Answer 1

The brain stem is critical to survival because it controls basic life-sustaining functions like breathing and heart rate.

Step-by-step explanation:

The brain stem is critical to survival because it controls basic life-sustaining functions like breathing and heart rate. These functions are regulated by the medulla oblongata, which is one of the components of the brain stem. The medulla oblongata receives sensory information from the body and sends motor commands to muscles and organs, ensuring that essential processes are maintained.
