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.
baroreflex baroreflex bar·o·re·flex (bār’ō-rē’flěks’) n. A reflex triggered by stimulation of a baroreceptor.
an instrument showing roughly the variations in atmospheric pressure. Historical Examples In my baroscope, I have never found the Quicksilver higher than 30. Philosophical Transactions of the Royal Society – Vol 1 – 1666 Various Sometimes (I say not often) the baroscope yields not to other very great changes of the Air. Philosophical Transactions of […]
aerosinusitis. barosinusitis bar·o·si·nus·i·tis (bār’ō-sī’nə-sī’tĭs) n. See aerosinusitis.
inflammation of the nasal sinuses caused by the effect on the sinuses of changes in atmospheric pressure. aerosinusitis aer·o·si·nus·i·tis (âr’ō-sī’nə-sī’tĭs) n. Inflammation of the paranasal sinuses caused by a difference between the pressure within the sinus cavities and the ambient pressure. Also called barosinusitis.
