The patient reports symptoms of chest pain, fatigue, and dizziness. Upon examination, his heart rate is 175/min and regular. His blood pressure is 110/75 mm Hg. Gentle massage below the level of the left mandible elicits an immediate improvement in the patient, as his heart rate returns to 70/min. What was the mechanism of action of this maneuver?

Where are baroreceptors located?Baroreceptors are stretch-sensitive fibers located primarily in the aortic arch and each of the carotid sinuses near the area where the common carotid artery bifurcates [10].
What are baroreceptors and where are they located quizlet?Baroreceptors are located in the walls of the carotid arteries and aorta. The carotid baroreceptors monitor pressure of blood flowing to the brain whereas the aortic baroreceptors monitor pressure of blood flowing to the body.
What are baroreceptors?Baroreceptors are a type of mechanoreceptor allowing for the relay of information derived from blood pressure within the autonomic nervous system. They are spray-type nerve endings in the walls of blood vessels and the heart that are stimulated by the absolute level of, and changes in, arterial pressure.
