Term:sperm flagellum
go back to main search page
Accession:GO:0036126 term browser browse the term
Definition:A microtubule-based flagellum (or cilium) that is part of a sperm, a mature male germ cell that develops from a spermatid.
Comment:Note that cilia and eukaryotic flagella are deemed to be equivalent. In this case community usage is always 'flagellum', hence the primary term name, but the cilium parentage is deliberate.
Synonyms:exact_synonym: sperm cilium;   sperm tail
