Cross section the 9 + 2 axoneme of the cilium of Tetrahymena. The plasma membrane covers the axoneme and is continuous with the plasma membrane covering the cell body. Each doublet tilts inward to the...

Figure 340 from Chapter 14 (Sperm Flagellum) of 'The Cell, 2nd Ed.' by Don W. Fawcett M.D. Cross sections of sperm tails of a caddis fly illustrate differences between the organization of the insect ...

This electron micrograph shows a cross section through the midpiece of opossum sperm. Filamentous cytoplasm underlies a scalloped membrane with regular variations in thickness, which gives it a corrug...

High resolution micrograph of a cross section the 9 + 2 axoneme of the cilium of Tetrahymena. The plasma membrane covers the axoneme and is continuous with the plasma membrane covering the cell body. ...

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...

Figure 330 from Chapter 14 (Sperm Flagellum) of 'The Cell, 2nd Ed.' by Don W. Fawcett M.D. This electron micrograph shows a transverse section through the principle piece of Chinese hamster spermatoz...

Figure 329 from Chapter 14 (Sperm Flagellum) of 'The Cell, 2nd Ed.' by Don W. Fawcett M.D. This electron micrograph shows a transverse section through the midpiece of Chinese hamster spermatozoa. Im...

Figures 333 (left) and 334 (right) from Chapter 14 (Sperm Flagellum) of 'The Cell, 2nd Ed.' by Don W. Fawcett M.D. Left, longitudinal section of the junction of midpiece and principle piece from sper...

Figures 335 (upper) and 336 (lower) from Chapter 14 (Sperm Flagellum) of 'The Cell, 2nd Ed.' by Don W. Fawcett M.D. Upper, cross-section of guinea pig sperm tail at the level of the midpiece; lower, ...

Longitudinal section of somatic cilia showing the axoneme, basal body, and attached fibrous and microtubular elements. Standard glutaraldehyde fixation followed by osmium tetroxide, dehydrated in alco...
