A decrease in baroreceptor excitation due to a drop in blood pressure would result in which of the following?

Question

Quizplus · Accepted Answer

A decrease in baroreceptor excitation, due to a drop in blood pressure, would lead to a decrease in the inhibitory signals to the cardiovascular centers in the brainstem. This results in increased sympathetic activity and decreased parasympathetic activity. Consequently, there is an increase in heart rate and vasoconstriction, mediated by the release of norepinephrine from sympathetic postganglionic neurons, to raise blood pressure.
