Cellular component

9+0 immotile cilium, non-motile 9+0 cilium

A non-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 (authentic primary cilia in many cell types) or in multiple copies (e.g. in Grueneberg ganglion neurons).
