The inner segment of photoreceptors in the retina is packed with long, thin mitochondria that contain curved cristae. This image by Toichiro Kuwabara is of a photoreceptor from human retina, and appe...

Early transmission electron micrograph showing intracisternal granules with an electron density equal to that of zymogen granules found in rough endoplasmic the reticulum lumen (cisternae) of animals ...

Zero degree tilt image from a tilt series collected using an intermediate voltage electron microscope through +/- 60 degrees of mitochondria isolated from mouse liver. Section thickness was 0.5 um. Th...

Figure 232 from Chapter 7 (Mitochondria) of 'The Cell, 2nd Ed.' by Don W. Fawcett M.D. Dividing mitochondria in gasric mucosa of a mole. Upper panel, the bilaminar septum as formed, but the outer me...

The high wing beat frequency in insects is intense muscle work, and dependent on a ready supply of ATP. This micrograph of flight muscle from the moth, Phytometra gamma shows the physical relationship...

Transmission electron micrograph of guinea pig pancreas mitochondria and lipid droplets. The use of osmium tetroxide as a fixative for electron microscopy was first described by Dr. Palade at the Roc...

Drosophila melanogaster thoracic indirect flight muscle from a four week-old wild-type animal. A longitudinal section of myocyte is displayed. Sections of parallel myofibrils are visible between dense...
