The endothelium plays a critical role in controlling resistance artery diameter, and thus blood flow and blood pressure. Circulating chemical mediators and physical forces act directly on the endothelium to release diffusible relaxing factors, such as NO, and elicit hyperpolarization of the endothelial cell membrane potential, which spreads to the(More)
Agonist-induced vasoconstriction triggers a negative feedback response whereby movement of charged ions through gap junctions and/or release of endothelium-derived (NO) limit further reductions in diameter, a mechanism termed myoendothelial feedback. Recent studies indicate that electrical myoendothelial feedback can be accounted for by flux of inositol(More)
