Abstract

Cardiac muscle is made up of cross-striated fibres, quasi-cylindrical in shape, which bifurcate and connect with adjacent fibres to form a complex three-dimensional network (Figs. 2, 6, 8). Each fibre is a linear unit composed of several cardiac muscle cells joined end-to-end or end-to-side, in an interdigitating rectangular step-like manner, by specialized junctional complexes called intercalated discs (Figs. 6, 8, 12). Since individual muscle cells (myocytes) rarely branch, the bifurcation of fibres is mainly due to end-to-side interdigitations (see Sommer 1982).
