CentrosomeMicrotubule organizing centerCytoplasmCytoskeletonCentriole


The centriole is a barrel-shaped microtubule-based structure. A pair of centrioles, embedded in the so-called pericentriolar material, constitute the centrosome, a microtubule organizing center of an eukaryotic cell. Centrioles are barrel-shaped microtubule-based structures organized in a 9-fold radial symmetry. Centriolar microtubule arrays usually consist of triplet microtubules, although doublets or singlets are present in some species. Centrioles are structurally related to (and often interconvertible with) basal bodies, the organelles required for the assembly of a cilium or flagellum.
