An Increase in the Rate of Action Potentials from Baroreceptors

Question

An increase in the rate of action potentials from baroreceptors will trigger a reflex to
A) increase heart rate.
B) decrease heart rate.
C) decrease blood pressure.
D) both decrease heart rate and decrease pressure.
E) both increase heart rate and increase pressure.

Accepted Answer

An increase in the rate of action potentials from baroreceptors, which detect changes in blood pressure, triggers a reflex to decrease heart rate and decrease blood pressure to maintain homeostasis.
