Steriod-secreting cells exhibit unusual diversity in the cristae of their mitochrondria, like these examples from testicular Leydig cells of the ground squirrel Citellus lateralis. Small alveolar cri...

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 ...

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...

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...

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...
