Influence of ryanodine receptor agonist and antagonist on development of potassium contracture in phasic (twitch) and tonic fibers of frog skeletal muscle

We compared the influence of external calcium and the inhibitor (dantrolene) and activator (4-chloro-m-cresol) of ryanodine-sensitive Ca channels of the sarcoplasmic reticulum on the characteristics of potassium contracture in phasic and tonic frog skeletal muscle fibers. The duration of contracture...
