carotid sinus
A pocket in the wall of the carotid artery, at its division in the neck, containing receptors that measure blood pressure (see baroreceptor). When blood pressure is raised, impulses travel from the receptors to the vasomotor center in the brain, which initiates a reflex vasodilation and slowing heart rate to lower the blood pressure to normal.
