WebSep 24, 2024 · Myogenic tone was expressed as the percentage of passive diameter ((passive diameter - active diameter)/passive diameter x 100). Proximal cerebral arteries were carefully isolated and similarly proceeded on a video‐monitored arteriograph system (Living System; LSI, Burlington, VT) which allowed to measure changes in arterial internal … WebJul 18, 2024 · First, the myogenic response remains the most convincing explanation for the ability of the vascular system to maintain constant blood flow in the face of persistent variation in blood pressure. It creates a basal level of tone (myogenic tone) from which blood vessels can constrict further or dilate to regulate blood flow.
WebDec 31, 2013 · To eliminate the potential influence of endothelial factors on pressure-induced myogenic tone, an air bolus was passed through the lumen to disrupt the endothelium. PCA segments lacking a vasodilatory response to acetylcholine (1 µmol/L), but exhibiting efficient constriction to serotonin (10 µmol/L), were included in the studies. ...
