Cellular component

motile 9+0 cilium

A motile cilium where the axoneme has a ring of nine outer microtubule doublets but no central microtubules (and is therefore called a 9+0 axoneme).

This type of cilia may be present in solitary (classic nodal cilia in embryonic nodes) or in multiple copies (e.g. in the choroid plexus epithelium).
