The locomotor cortex of Didinium. A longitudinal section of basal bodies and the axonemes of cilia is revealed as they emerge from the cell cortex of Didinium. Bundles of microtubules extend from the ...

A high resolution image Didinium. This ciliate has two bands of ciliated basal bodies that encircle the cell, one adorally and one aborally. The bands are composed of groups of approximately 15 ciliat...

A cross section of cilium through the cilium-basal body complex extending from the cilium to the transition zone between the cilium and basal body and ending at the proximal tip of the basal body. In ...

Figure 328 from Chapter 14 (Sperm Flagellum) of 'The Cell, 2nd Ed.' by Don W. Fawcett M.D. Scanning electron micrograph of rabbit spermatozoa on the endometrium of the uterus. Image by David Phillip...

Transmission electron micrograph of longitudinal section through mouse spermatozoon showing characteristic hooked shape of sperm head and extremely compact DNA-protamine in the nucleus. Figure 117 fr...

Human sperm diluted in buffer imaged at room temperature within two hours of ejaculation. Cell at center swims at constant speed.

The electron micrograph shows the tip of a primary cilium in a testis cell in primary culture. The plasma membrane of the adjacent cell has a coated pit juxtaposed to the ciliary tip.

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, ...

Total internal reflection (TIRF) micrograph of MDCK cells stably transfected with the apical membrane protein P75-GFP (green) and stained for acetylated tubulin of the primary cilium (red) by immunofl...

Appriximately longitudinal section of the unicellular alga Chlamydomonas reinhardtii showing one of the paired flagella, and the spherical nucleus surrounded by the single cup-shaped chloroplasts cont...
