Figure 237 from Chapter 7 (Mitochondria) of 'The Cell, 2nd Ed.' by Don W. Fawcett M.D. Mitochondria in cells of brown adipose tissue (shown here in interscapular brown fat of the bat) are dense, and ...

Figure 240 from Chapter 7 (Mitochondria) of 'The Cell, 2nd Ed.' by Don W. Fawcett M.D. The shape of mitochondrial cristae can vary with cell type, shown here in a cell from hamster adrenal cortex. Fo...

A lattice arrangement of mitochondria is rare in vertebrate cells, but can be observed here in mature Sertoli cells of the Xenopus testes. Multiple parallel fenestrated layers of cristae are interconn...

The midpiece of spermatzoa in nearly all vertebrates is enclosed in a sheath of mitochondria, which provide a ready source of ATP necessary for sperm motility. Here, a longitudinal section through sp...
