Stimulation of the Aortic Baroreceptors Reflexively Results In

Question

Stimulation of the aortic baroreceptors reflexively results in
A) stimulation of the cardioaccelerator center in the brain.
B) increased sympathetic stimulation of the heart.
C) increased activity by the parasympathetic nervous system.
D) stimulation of the vasoconstrictive center.
E) increased heart rate.

Accepted Answer

Stimulation of the aortic baroreceptors, which detect changes in blood pressure, reflexively results in increased activity by the parasympathetic nervous system. This response aims to lower blood pressure by reducing heart rate and force of cardiac contractions.
