What are the differences in the excitation-contraction coupling between smooth
muscle and skeletal muscle?
The sequence of events that connects the action potential (excitation) of the muscle cell membrane (the
sarcolemma) to muscular contraction is known as excitation-contraction coupling (E-C). Although the
myocardium's E-C coupling resembles that of skeletal and smooth muscle in many ways, there are also
significant differences.
