Quick-frozen deep-etched preparation of skeletal muscle tissue shows the muscle fiber and associated extracellular components. The basement membrane (labeled basal lamina) lies adjacent to the undulat...

Mouse skeletal muscle. This image depicts a transmission electron micrograph of 1 month old mouse skeletal muscle tissue from the EDL muscle. Note the highly ordered organization of the contractile ap...

Figure 429 from Chapter 16 (Cytoplasmic matrix and cytoskeleton) of 'The Cell, 2nd Ed.' by Don W. Fawcett M.D. A high magnification image showing interdigitation between actin and myosin filaments at...

Figure 351 from Chapter 15 (Cytoplasmic Inclusions) of 'The Cell, 2nd Ed.' by Don W. Fawcett M.D. Glycogen in the ventricle papillary muscle of cat heart. In this tissue, the glycogen occurs as indi...

Single computed slice from a tomographic reconstruction of a 500 nm section through the middle free wall of a cardiac myocyte from the left ventricle of an adult mouse (6-8 months of age), stained wit...

Cultured chicken embryonic cardiomyocyte transfected with GFP control vector in the nucleus, stained with alpha-actinin at the Z-lines in red and Tropomodulin1 (at the pointed ends of the actin filame...

Transmission electron micrograph of ventricle tissue of a mouse cardiac muscle. This image shows the intercalated discs between the muscle fibers as well as many mitochondria and lipid droplets.
