The role of calcium entry in cardiac excitation-contraction coupling was subsequently explained by the finding that calcium release from the cardiac SR, unlike that of skeletal muscle, depends on a small calcium influx across the plasma membrane in a process called âcalcium-triggered calcium releaseâ. 36 Calcium release from the cardiac SR, which causes localized âcalcium sparksâ that can be visualized when cells are injected with calcium-sensitive dyes, 37 38 is a critical ...
Contraction of Smooth Muscle. Myosin filaments in smooth muscle are also activated by increases in cytosolic calcium but by a different mechanism than in skeletal/cardiac muscle. Seven transmembrane receptors trigger signaling cascades that lead to increases in cytosolic calcium. Contrast the organization of myosin and actin filaments in smooth muscle with skeletal/cardiac muscle. 2  List the events from release of acetylcholine to contraction of sarcomeres in skeletal muscle cells.
