Myogenic feedback

WebJan 1, 2007 · Autoregulation of renal blood flow (RBF) is caused by the myogenic response (MR), tubuloglomerular feedback (TGF), and a third regulatory mechanism that is independent of TGF but slower than MR. The underlying cause of the third regulatory mechanism remains unclear; possibilities include ATP, ANG II, or a slow component of MR. WebThe myogenic mechanism results from the vascular smooth muscle contracting when stretched. The tubuloglomerular feedback mechanism that results in the macular densa cells responding to the filtrate’s high sodium concentration by releasing paracrine agent, that causes vasodialation diameter of the afferent arterioles and reduces blood flow.

WebAutoregulation. Autoregulation is a process within many biological systems, resulting from an internal adaptive mechanism that works to adjust (or mitigate) that system's response to stimuli. While most systems of the body show some degree of autoregulation, it is most clearly observed in the kidney, the heart, and the brain. [1] Perfusion of ...

Tetrandrine inhibits cancer cell proliferation and induces cell death through apoptosis and autophagy. As cancer patients usually experience complications with sarcopenia or muscle injury, we thus assessed the … 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.
