Editing Flagellum (section)

====Terminology====
Aiming to emphasize the distinction between the bacterial flagella and the eukaryotic cilia and flagella, some authors attempted to replace the name of these two eukaryotic structures with "[[undulipodium|undulipodia]]" (e.g., all papers by [[Lynn Margulis|Margulis]] since the 1970s)<ref name="pmid14657097">{{cite journal |last1=Taylor |first1=F J R Max |title=The collapse of the two-kingdom system, the rise of protistology and the founding of the International Society for Evolutionary Protistology (ISEP) |journal=International Journal of Systematic and Evolutionary Microbiology |date=1 November 2003 |volume=53 |issue=6 |pages=1707–1714 |doi=10.1099/ijs.0.02587-0 | pmid = 14657097 |doi-access=free}}</ref> or "cilia" for both (e.g., Hülsmann, 1992;<ref>{{cite journal |last1=Hülsmann |first1=Norbert |title=Undulipodium: End of a useless discussion |journal=European Journal of Protistology |date=August 1992 |volume=28 |issue=3 |pages=253–257 |doi=10.1016/s0932-4739(11)80231-2 | pmid = 23195228}}</ref> Adl et al., 2012;<ref name = "Adl_2012">{{cite journal |last1=Adl |first1=Sina M. |last2=Simpson |first2=Alastair G.
