pressoreceptor nerve

(redirected from baroreceptor nerve)

pres·so·re·cep·tor nerve

a nerve composed of afferent fibers the endings of which are sensitive to increases in mechanical pressure; the term specifically refers to sensory nerves innervating the walls of hollow organs.

Since our data indicate that hSOD1 overexpression did not cause dysfunction of MAP, HR, and BRS but may increase aortic baroreceptor nerve function, we suggest that this model can be potentially used to study whether increased expression of hSOD1 protects against disease (such as chronic intermittent hypoxia and diabetes-) induced impairment of baroreflex sensitivity, vagal motor neuron death in the nucleus ambiguus, and degeneration of vagal afferent and efferent axons in the aortic arch and cardiac ganglion shown in the previous studies [51, 52, 55, 84-86].
It should be pointed out that since baroreflex-mediated reduction of heart rate in response to increased arterial pressure had a trend of increase but not significantly, it appears that the increased signaling from the aortic depressor baroreceptor nerves to the brainstem is buffered by other neural components of the baroreflex loop, such as the NTS, NA, or cardiac ganglia within the heart.
