Only cardiac muscle has this particular appearance, which is given to it by something called intercalated discs. Cardiac muscle also consists of single muscle cells, called Cardiomyocytes; where something such as skeletal muscle cells are MULTInucleated (more than one cell nucleus).

This photo displays cardiac muscle tissue. This tissue type is striated, branched, and has 1-2 nuclei. Cardiac muscle tissue can be recognized by intercalated disks (dark thickened part). Cardiac muscle cells are bigger than smooth muscle cells and smaller than skeletal muscle cells. They control involuntary movement (the heart).

Growth of the zebrafish heart from embryo to adult is tracked using colored cardiac muscle clones, each containing many cellular progeny of a single cardiac muscle cell.  Here, a large clone of green cardiac muscle cells (top) expands over the surface of many smaller clones in a growing heart. Photo credit: Vikas Gupta

mitochondria packed between myofibrils in cardiac muscle the crystalline appearance of the numerous mitochondria is a result of densely packed cristae or infoldings of the inner membrane this design dramatically increases the surface area of the inner mitochondrial membrane in which ATP-producing machinery is embedded colored TEM credit: Science Photo Library
