Long- and short-term blood pressure regulation by arterial baroreceptors. Loss of parasympathetic input as well as loss of afferent stimulus in cases of baroreceptor denervation results in an abrupt increase in the MAP. Baroreceptors then rapidly reset and the blood pressure returns to pre-denervation levels. However, baroreceptors participate in long-term blood regulation. Experimental evidence indicates that in cases of catecholamine secretion, volume overload or increased angiotensin II secretion, increased baroreceptor pathway activity is followed by diminished sympathetic output and pressure normalization.
