Light microscopy of cardiac (heart) muscle seen at left in longitudinal section and in cross-section at the right. Heart muscle cells are striated, branched and joined end-to-end by tight junctions called intercalated discs that also serve as electrical impulse transmission between cells. Cell nucleus is central. Dark purple structures are mitochondria. Magnification x450 when printed at width 10 cm.
