<P> Arterial baroreceptors are stretch receptors that are stimulated by distortion of the arterial wall when pressure changes . The baroreceptors can identify the changes in both the average blood pressure or the rate of change in pressure with each arterial pulse . Action potentials triggered in the baroreceptor ending are then directly conducted to the brainstem where central terminations ( synapses ) transmit this information to neurons within the solitary nucleus . Reflex responses from such baroreceptor activity can trigger increases or decreases in the heart rate . Arterial baroreceptor sensory endings are simple , splayed nerve endings that lie in the tunica adventitia of the artery . An increase in the mean arterial pressure increases depolarization of these sensory endings , which results in action potentials . These action potentials are conducted to the solitary nucleus in the central nervous system by axons and have a reflex effect on the cardiovascular system through autonomic neurons . Hormone secretions that target the heart and blood vessels are affected by the stimulation of baroreceptors . </P>
