Baroreceptor
Reflex responses from such baroreceptor activity can trigger increases or decreases in the heart rate. If blood pressure falls, such as on orthostatic hypotension or in hypovolaemic shock, baroreceptor firing rate decreases and baroreceptor reflexes act

Baroreflex
While the carotid sinus baroreceptor axons travel within the glossopharyngeal nerve (CN IX), the aortic arch baroreceptor axons travel within the vagus Even at resting levels of blood pressure, arterial baroreceptor discharge activates SN neurons.

Bainbridge reflex
Control of heart rate
The Bainbridge reflex and the baroreceptor reflex control heart rate. The baroreceptor reflex can correct for a change in arterial pressure by increasing or decreasing heart rate.

Reflex bradycardia
Reflex bradycardia is a bradycardia (decrease in heart rate) in response to the baroreceptor reflex, one of the body's homeostatic mechanisms for preventing In the presence of high mean arterial pressure, the baroreceptor reflex produces a reflex bradycardia as a method of decreasing blood pressure by decreasing

Vagal maneuver
Vagal maneuvers may decrease temporary pain through sinoaortic baroreceptor mediated anti-nociception (inhibition of pain conduction, release of substance Vagal maneuvers make use of the vagus nerve's afferent and efferent bifunctional role, triggering reflexes (like the baroreceptor reflex, chemoreceptor

Antianginal
In vivo, the vasodilation and hypotension trigger the baroreceptor reflex. Therefore, the net effect is the interplay of direct and reflex actions.

Phentolamine
This hypotension is sensed by the baroreceptor reflex, which results in increased sympathetic nerve firing on the heart, releasing norepinephrine.
