WebJul 22, 2024 · Myogenic Theory This theory states that contraction or relaxation of smooth muscles around the walls of arteries regulates the changes in the blood pressure. Thus contraction and relaxation at an appropriate time can restore the blood pressure to the normal. Metabolic Theory 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. Most often observed in (although not necessarily restricted to) smaller resistance arteries, this 'basal' myogenic tone may be useful in the regulation of organ blood flow …

WebThe myogenic theory is the most widely accepted explanation for the mechanism of autoregulation. A metabolic hypothesis has also been described, but is better suited as a description of metabolic-flow coupling rather than autoregulation.
