Radial Spokes are found within the axoneme of a eukaryotic cilium or flagellum. They are inward projections coming from each of the nine outer microtubule pairs around the axoneme towards the centre doublet. They are thought to convert the sliding movement of the doublets into the bending motion of cilia and flagella that characterises their beating.
