Description

Figures 342 (upper) and 343 (lower) from Chapter 14 (Sperm Flagellum) of 'The Cell, 2nd Ed.' by Don W. Fawcett M.D. Cross sections of spermatozoa from the caddis fly (Polycentropus, upper) and mosquito (Culex, lower) provide examples of variation in the microtuble organization of motile flagella. In contrast to common 9 + 2, or 9 + 9 + 2, the caddis fly shows a 9 + 7 organization, whereas the mosquito exhibits 9 + 9 + 1 pattern. Images by David Phillips; Fig 343 from Phillips, J. Cell Biol. 40:28-43, 1969. A PDF copy of the accompanying chapter is available on the ASCB’s BioEDUCATE website.
