Schematic diagram showing the essential pathways that subserve the baroreflex control of the sympathetic outflow to the heart and blood vessels and the parasympathetic outflow to the heart. The baroreceptors are stretch receptors located in the walls of the carotid sinus and aortic arch (not shown). CVLM, caudal ventrolateral medulla; IML, intermediolateral cell column; NA, nucleus ambiguous; NTS, nucleus tractus solitaries; RVLM, rostral ventrolateral medulla; X, vagus nerve.
