Heart muscle cell. Coloured transmission electron micrograph of a heart muscle cell (cardiomyocyte),showing enormous numbers of mitochondria (blue),required for a constant energy supply to sustain heart muscle contractions. Myofilament proteins (light blue),made up of mysosin and actin,enable the muscle to contract. All cardiomyocytes are joined end-to-end by special intercellular junctions. Gap junctions enable cell-to-cell electrical conduction which is the basis for the coordinated and rhythmic contraction of heart muscle | |
