Smooth muscle action potential
Web4 Aug 2003 · smooth muscle contracted to many different agonists. In the intact animal, the pharmacological inhibitors of Rho kinase have been shown to cause relaxation of smooth muscle in arteries, resulting in a blood pres-sure-lowering effect (2, 17). An important question facing the smooth-muscle physiologist is: what is the link between receptor WebA. action potential frequency is high enough that no relaxation of muscle fibers occurs. B. a muscle produces constant tension during contraction. C. a muscle produces an increasing tension as the length remains constant. D. a muscle produces increasing tension as …
