Cardiac Centers _______

Question

Cardiac centers _______.
A) control autonomic nerves that signal the SA node
B) are located in the midbrain
C) are regulated by acetylcholine
D) answers A and B are correct

Accepted Answer

Cardiac centers are responsible for controlling autonomic nerves that signal the SA node, which regulates the heart rate. They are located in the medulla oblongata of the brain, not the midbrain. While acetylcholine is involved in regulating the heart rate, it is not the only regulator and is not directly related to cardiac centers.
