vasomotor: [ vas″o-mo´tor ] 1. having an effect on the caliber of blood vessels; see also vasoactive . 2. a vasomotor nerve.

The vasomotor center receives sensory input from the peripheral baroreceptors and chemoreceptors, the cortex, hypothalamus, pain pathways and muscles. However, it is the baroreceptors which play the pivotal role in daily cardiovascular homeostasis – maintaining the blood pressure within a narrow range.

Excitation of the vasomotor center results in: a. increased sympathetic activity and predominantly more vasoconstriction than vasodilation. b. increased parasympathetic activity and predominantly more vasodilation than vasoconstriction.

Excitation of the vasomotor center results in

increased sympathetic activity and predominantly more vasoconstriction than vasodilation. b. increased parasympathetic activity and predominantly more vasodilation than vasoconstriction. c. increased autonomic activity that increases heart rate and dilates blood vessels. 1. excitation of vasomotor center by carotid body chemoreceptor signaling The process in which the molecular signal from a carotid body is relayed to the vasomotor center, causing it to signal an increase arterial pressure.

Vasomotor center controls of the hepatic circulation during blood pressure oscillation in rabbits. Takeuchi T, Terada N, Koyama S. Changes in hepatic hemodynamics during blood pressure oscillations caused by the side pressure exertion procedure (SPEP) were studied in anesthetized rabbits.

However, it is the baroreceptors which play the pivotal role in daily cardiovascular homeostasis – maintaining the blood pressure within a narrow range. 2020-10-05 1953-01-01 These results are consistent with a large body of research that shows the vasomotor response to be a valuable contribution to physiological deception detection.

"Vasomotor centre" is a term which usually refers to the central control centres which regulate the reflex adjustment of heart rate and blood pressure. These centres include the nucleus of the solitary tract which processes afferent input, the nucleus ambiguus which mediates vaga efferent output, and the caudal and rostral ventrolateral medulla (CVLM and RVLM) which maintain a constant

Excitation of the vasomotor center results in

Synonym: excitation of vasomotor center by chemoreceptor signalling; Type: pathway; Taxonomic scope: conserved biosystem; BSID: 487898 GO: GO:0002008. Excitation of the vasomotor center results in: a. increased sympathetic activity and predominantly more vasoconstriction than vasodilation.

Particularly striking results are seen when a test stimulus of near-threshold intensity is chosen, and also when the stimulus is applied early in asphyxia before signs of sympathetic excitation are manifest. The cardioinhibitor centers slow cardiac function by decreasing heart rate and stroke volume via parasympathetic stimulation from the vagus nerve.

Control of vasomotor center by higher nervous centers and vasomotor centers, this chemoceptive influence is opposite in sign to that exerted by the sinoaortic presso- ceptors, being excitatory in nature. Received for publication g November 1960. l This research has been sponsored in part by Wright Air De- velopment Center, Aeromedical Laboratory, Air Research and 1995-10-06 · The evoked excitation of these reticulospinal vaso- motor neurons is the result of an activation of excitatory amino acid synaptic inputs onto them, via acting on the N-methyl-L-aspartate (NMDA) receptors of the neurons (Sun and Reis, 1995). explanation of the apparent vasomotor inac-tivity may be the loss of the activity of the skin vessels in such a perfused limb. On the other hand, after the center has been impaired by several slow hemorrhages, a point is reached when further bleeding leads to a failure of the vasomotor mechanism1"1 (fig. 4). This vasodilatation is then, not entirely a 2021-02-03 · The vasomotor center is a group of sympathetic nerve cells contained within the medulla oblongata, a structure of the brainstem.

From their surface, impulses rise along the vagus and depressor nerves to the vasomotor center. In this case, the activity of the depressor part of this department is intensified. As a result, the vessels relax and lower blood pressure. Vasodilation is also caused by the activation of the nuclei of the vagus nerves. Changes in vasomotor center tone
