<cell biology> Motile appendage of eukaryotic cells that contains an axoneme, a bundle of microtubules arranged in a characteristic fashion with nine outer doublets and a central pair (9+2 arrangement).

Active sliding of doublets relative to one another generates curvature and the asymmetric stroke of the cilium drives fluid in one direction (or the cell in the other direction).
