  • Excitation Contraction Couplingan overview

    Excitation–contraction (e–c) coupling is the term used to describe the progression from membrane excitation with an AP to the rise of the Ca transient to myocyte contraction. The time course of e–c coupling can be observed for a mammalian myocyte in Figure 1. Notice the central role of the Ca transient (blue line).
