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.
[G. baros, weight, + receptor]

baroreceptor

(băr′ō-rĭ-sĕp′tər) or

baroceptor

(băr′ō-sĕp′tər)
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 reflex mechanisms that tend to reduce that pressure.

baroreceptor

(băr′ə-rĭ-sĕp′tər)
n.
A sensory nerve ending that is stimulated by changes in pressure, especially one in the walls of blood vessels such as the carotid sinus.

baroreceptor

A cluster of mechanoreceptors in the atrium, vena cava, aortic arch and carotid sinus, which are sensitive to tissue stretching that occurs with increased intravascular pressure; baroreceptor information passes to the brainstem from the carotid sinus via the glossopharyngeal nerve and from the aortic arch and great vessels of the thorax via the vagal nerve.

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.

BARORECEPTOR
A sensory nerve ending stimulated by changes in pressure. Baroreceptors are found in the walls of the cardiac atria, the vena cava, aortic arch. The baroreceptors of the lung are stretch receptors that are stimulated by inflation. Synonym: barostat; pressoreceptor See: illustration

baroreceptor

A nerve ending which produces an output when there is a change in ambient pressure. Also known as baroceptor.

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.
