DictionarySeebaroreceptorbaroceptor
baroreceptor [bar″o-re-sep´ter] a sensory nerve terminal that is stimulated by changes in pressure, as those in blood vessel walls. Called also baroceptor and pressoreceptor.bar·o·re·cep·tor (bar'ō-rē-sep'ter, -tōr), 1. In general, any sensor of pressure changes. 2. Sensory nerve ending in the wall of the atrium of the heart, vena cava, aortic arch, and carotid sinus, sensitive to stretching of the wall resulting from increased pressure from within and functioning as the receptor of central reflex mechanisms that tend to reduce that pressure. Synonym(s): baroceptor, pressoreceptor [G. baros, weight, + receptor] bar·o·re·cep·tor (bar'ō-rĕ-sep'tŏr) 1. In general, any sensor of pressure changes. 2. Sensory nerve ending in the cardiac atria, vena cava, aortic arch, and carotid sinus, sensitive to stretching of the wall resulting from increased pressure from within, and functioning as the receptor of central reflex mechanisms that tend to reduce that pressure.
Synonym(s): baroceptor, pressoreceptor. [G. baros, weight, + receptor]baroreceptor or baroceptor a pressure RECEPTOR that responds to changes in blood pressure, found particularly in the carotid sinus and aortic arch.bar·o·re·cep·tor (bar'ō-rĕ-sep'tŏr) In general, any sensor of atmospheric pressure changes.
Synonym(s): pressoreceptor. [G. baros, weight, + receptor] |
