baroreceptor

baroreceptor /baro·re·cep·tor/ (-re-sep´ter) a type of interoceptor that is stimulated by pressure changes, as those in blood vessel walls.

bar·o·re·cep·tor (br-r-sptr) or bar·o·cep·tor (br-sptr)

n.

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.

baroreceptor

[ber′ōrisep′tər]

Etymology: Gk, baros + L, recipere, to receive

one of the pressure-sensitive nerve endings in the walls of the atria of the heart, the aortic arch, and the carotid sinuses. Baroreceptors stimulate central reflex mechanisms that allow physiologic adjustment and adaptation to changes in blood pressure via changes in heart rate, vasodilation, or vasoconstriction. Baroreceptors are essential for homeostasis. Also called pressoreceptor.
