Cardiac Muscle Electron Micrograph
Electron micrograph of parts of three cat cardiac muscle fibers and an adjacent capillary in longitudinal section. This is a historic (1969) EM showing key features in cat cardiac ventricular muscle ultrastructure. Only the intercalated disc and some cross-striations can typically be seen in the light microscope histology slides.
Legend
- In D - Intercalated disc, the two lower cells are joined end to end by a typical steplike intercalated disc.
- Mt - Rows of mitochondria appear to divide the contractile substance into myofibril-like units but, unlike the true myofibrils of skeletal muscle, these branch and rejoin and are quite variable in width.
- Lp - Lipid droplets somewhat distorted in specimen preparation are found between the ends of the mitochondria.
- Cap - Capillary.
