Increasing the mean arterial pressure or the pulse pressure in the carotid artery will cause decreased firing of action potentials in the afferent neurons associated with the baroreceptors.

Question

Quizplus · Accepted Answer

Increasing mean arterial pressure or pulse pressure in the carotid artery would stimulate the baroreceptors and increase the firing of action potentials in the afferent neurons. This increase in firing would then lead to a reflex decrease in sympathetic outflow and an increase in parasympathetic outflow, ultimately causing vasodilation and a decrease in blood pressure.
