Abstract:The three-dimensional structure of the sarcoplasmic reticulum (SR), transverse (T)-axial tubular system and mitochondria in cardiac and skeletal muscle fibers of the rat was examined by ultra-high resolution scanning electron microscopy after removal of the cytoplasmic matrices and myofilaments by the aldehyde-osmium-dimethyl sulfoxide-osmium procedure1,2. Between the cardiac and the skeletal muscle fibers, striking differences in the three-dimensional structure of the mitochondria and of the SR were observed.
