Carotid-sinus
specialized nerve end organs producing a slight dilatation of the carotid artery where it branches into the external and internal carotid arteries, responding to changes in blood pressure by mediating changes in the heartbeat rate.
carotid sinus n.
A dilation of the common carotid artery at its bifurcation into the internal and external carotids, containing baroreceptors that when stimulated cause slowing of the heart, vasodilation, and a fall in blood pressure.
carotid sinus
A dilated region that is located at the point of bifurcation of the carotid artery and contains pressure receptors (called baroreceptors), which upon stimulation cause slowing of the heart rate, vasodilation, and a decrease in blood pressure.
