The function of this structure takes place during the very last stage of cell division, called cytokinesis. The complex, formed together with centrioles and centrosphere, is called the centrosome. Inside the cilia or flagella there are doublets of microtubules surrounding another doublet in the center, making them structurally different from centrosome microtubules. Beyond the microtubule triplets of the centriole, we discuss the critically important cartwheel structure and the more enigmatic luminal density, both found on the inside of the centriole. A centriole is the main unit that creates and anchors microtubules in the cell.
