Movie of portion of a hypermastigote symbiont from the hindgut of a wood eating cockroach. The rootlets and flagella are birefringent and the beating flagella are clearly seen with the polarizing micr...

The unicellular alga Chlamydomonas reinhardtii has a pair of anterior flagella that function in motility. In this image, the base of the flagella with basal bodies and associated structures are are cu...

Figs. 315 from Don Fawcett's Chapter 12 (Centrioles). The dense material that forms the capitulum and the cross-striated columns of the connecting piece in spermatozoa is formed in intimate associatio...

Figure 322 from Chapter 13 (Cilia and Flagella) of 'The Cell' by Don W. Fawcett M.D. Cilia and flagella usually occur on motile cells or on the free surfaces of epithelia. However, a solitary cilium i...
