真核鞭毛的示意圖。 1-軸絲,2-細胞膜,3-IFT(鞭毛內運輸(英語:Intraflagellar transport)),4-基體,5-鞭毛的橫切面,6-基體的三微管。Longitudinal section through the flagella area in Chlamydomonas reinhardtii. In the cell apex is the basal body that is the anchoring site for a flagellum. Basal bodies originate from and have a substructure similar to that of centrioles, with nine peripheral microtubule triplets (see structure at bottom center of image).
