Abstract

Numerous cellular structures are involved with the process of excitation-contraction coupling (E-C coupling) in cardiac muscle cells. This chapter serves to introduce some of these components from an ultrastructural perspective, and key functional components will be discussed in greater detail in subsequent chapters. Figures 1 and 2 are schematic drawings of the structure of amphibian skeletal muscle (Fig 1) and mammalian ventricular muscle (Fig 2) from a classic ultrastructural study by Fawcett & McNutt (1969; also based on the work of Peachey, 1965).
