Definition

The cilium axoneme is the most prominent structural component of the cilium. It consists of nine doublet microtubules, with all motile cilia - except those at the embryonic node - containing an additional central pair of microtubules. The axonemal microtubules of all cilia nucleate and extend from a basal body, a centriolar structure most often composed of a radial array of nine triplet microtubules. In most cells, basal bodies associate with cell membranes and cilia are assembled as 'extracellular' membrane-enclosed compartments.
