Skeletal muscle excitation-contraction (EC) coupling roots in Ca2+-influx-independent inter-channel signaling between the sarcolemmal dihydropyridine receptor (DHPR) and the ryanodine receptor (RyR1) in the sarcoplasmic reticulum. Although DHPR Ca2+ influx is irrelevant for EC coupling. its putative role in other muscle-physiological and developmental pathways was recently examined us... https://lecoureures.shop/product-category/ski-de-fond-homme-vetements-chandail/
