Centriole—a short cylindrical assembly of microtubules arranged in nine groups of three microtubules each
Two centrioles lie perpendicular to each other within a small, clear area of cytoplasm called the centrosome
Play role in cell division
Cilia and flagella formation
Each basal body of a cilium or flagellum is a single centriole oriented perpendicular to plasma membrane
Basal bodies originate in centriolar organizing center
Migrate to plasma membrane
Two microtubules of each triplet elongate to form the nine pairs of peripheral microtubules of the axoneme
Cilium reaches full length in less than an hour
