Definitions related to baroreflex:
-
A response by the BARORECEPTORS to increased BLOOD PRESSURE. Increased pressure stretches BLOOD VESSELS which activates the baroreceptors in the vessel walls. The net response of the CENTRAL NERVOUS SYSTEM is a reduction of central sympathetic outflow. This reduces blood pressure both by decreasing peripheral VASCULAR RESISTANCE and by lowering CARDIAC OUTPUT. Because the baroreceptors are tonically active, the baroreflex can compensate rapidly for both increases and decreases in blood pressure.NLM Medical Subject HeadingsU.S. National Library of Medicine, 2021
-
Reflex slowing of the heart rate caused by pressure on, or in, the carotid artery.CRISP ThesaurusNational Institutes of Health, 2006
