General Information
Term cilium ID (Ontology) GO:0005929 (Gene Ontology)
Definition A specialized eukaryotic organelle that consists of a filiform extrusion of the cell surface and of some cytoplasmic parts. Each cilium is largely bounded by an extrusion of the cytoplasmic (plasma) membrane, and contains a regular longitudinal array of microtubules, anchored to a basal body.[ ISBN:0198547684 PubMed:16824949 PubMed:17009929 PubMed:20144998 ]
Also Known As "eukaryotic flagellum" ; "microtubule-based flagellum"
