In a myocyte this structure stores calcium
WebStore-operated calcium influx has emerged as a mechanism by which calcium signaling pathways are activated in order to respond to the changing demands of the myocyte. … WebCalcium-induced calcium release is a general mechanism that most cells use to amplify Ca++ signals. In heart cells, this mechanism is operative between voltage-gated L-type Ca++ channels (Ca v 1), located in the plasma membrane, and ryanodine receptor channels, located in the sarcoplasmic reticulum.
