left caudal flagellum cellular_component GO:0097560 2014-02-05T13:29:44Z left caudal cilium A cilium (also called flagellum) found in Giardia species (trophozoite stage). It is nucleated by the left caudal basal body, extending cytoplasmically and exiting at the posterior end of the cell body. pr Note that we deem cilium and microtubule-based flagellum to be equivalent; the primary term name reflects frequency of use. Also note that, due to the asymmetric nature of the Giardia trophozoite, this term is defined spatially as the trophozoite is viewed from the dorsal side, with the two nuclei dorsal to the ventral disc, and the ventral disc toward the anterior. 9+2 motile cilium
