Myogenic hypothesis
The myogenic mechanism is how arteries and arterioles react to an increase or decrease of blood pressure to keep the blood flow constant within the blood vessel. Myogenic response refers to a contraction initiated by the myocyte itself instead of an outside occurrence or stimulus such as nerve innervation. … See more Bayliss effect or Bayliss myogenic response is a special manifestation of the myogenic tone in the vasculature. The Bayliss effect in vascular smooth muscles cells is a response to stretch. This is especially relevant in See more • Moore L.C., A. Rich, and D. Casellas.

WebAccording to the myogenic hypothesis, changes in CPP directly influence alterations in vascular smooth muscle tone independent of extrinsic factors. However, autonomic innervation of cerebral blood vessels might also contribute to autoregulation (discussed in … WebThe myogenic component not only maintains blood flow despite changes in the perfusion pressure but also helps in facilitating blood flow either during the increased metabolic …
WebNumerous mechanisms may influence cerebral vascular tone. 31, 34 The myogenic hypothesis holds that the smooth muscle of the cerebral arteries and arterioles changes tone reflexly, as evidenced by the near-immediate response to changes in blood pressure. Proponents of the metabolic hypothesis point to the proportionality between cerebral … WebJul 7, 2000 · The myogenic response contributes to autoregulation of blood flow and is believed to be one of the primary mechanisms responsible for the basal tone of small …
WebWe tested the hypothesis that older males (OMs, 70±4 yr, n=9) would have a blunted myogenic response to a physiological stimulus compared to younger controls (21±3 yr, n=9). Subjects completed an acute bout of intense unilateral muscle loading. Young healthy males matched for body mass and activity level served as the control group.

WebAug 1, 2001 · Previous studies support the hypothesis that muscle precursor cells, including the myogenic satellite cell population, originate from the multipotential mesodermal cells of the somite (58, 141,167). The support for this hypothesis is primarily derived from chimeric or interspecies grafting experiments that have been performed in avian models.
