Colorized scanning electron micrograph of thigh muscle fibrils.

Lipid droplets partially enveloped by mitochondria in the interstices between cardiac myofibrils reveal a metabolic partnership that can serve as an alternative energy source for muscle. Figures 255 ...

In cardiac muscle, mitochondria are distributed uniformly in a near-continuous field of myofilaments, ensuring that ATP is readily available. This transverse section is of right ventricular papillary...

Transmission electron micrograph of rat heart cardiac muscle from the atrium showing the regular arrangement of the actin-myosin myofilaments in cross section and abundant mitochondria. This 1958 TE...

Transmission electron micrograph of longitudinal section of rat cardiac muscle from the atrium. A of group of horizontally-running myofibrils is seen at the top. Also prominent are numerous glycogen...

Drosophila melanogaster thoracic tergotrochanter muscle from a four week-old wild-type animal. A longitudinal section of myocyte is displayed. Sections of parallel myofibrils are seen with distinguish...
