An expanded part attached to the chrotid artery, which monitors blood pressure in the skull.
A pocket in the wall of the carotid artery, at its division in the neck, containing receptors that monitor blood pressure. When blood pressure is raised, impulses travel from the receptors to the vasomotor center in the brain, which initiates a reflex vasodilatation and slowing of heart rate to lower the blood pressure to normal.
The site at the base of the internal carotid artery of pressoreceptors innervated by the glossopharyngeal nerve. These receptors detect changes in blood pressure and bring about reflex changes in heart rate and arterial diameter.
The region where the carotid artery splits into the internal and external carotid arteries, and it is abundantly supplied with nerves.
