a nerve ending, as one of those located in the blood vessels, that responds to changes in pressure.
a collection of sensory nerve endings, principally in the carotid sinuses and the aortic arch, that monitor blood pressure changes in the body

baroreceptor bar·o·re·cep·tor (bār’ō-rĭ-sěp’tər) or bar·o·cep·tor (bār’ō-sěp’tər)
A sensory nerve ending in the walls of the auricles of the heart, vena cava, carotid sinus, and aortic arch, sensitive to stretching of the wall due to increased pressure from within, and functioning as the receptor of central reflex mechanisms that tend to reduce that pressure. Also called pressoreceptor.
A cell or sense organ found in the walls of the body’s major arteries and stimulated by changes in blood pressure. Signals from baroceptors lead to a reduction in arterial blood pressure.
