Microtubules are one of the components of the cytoskeleton. They are present as hollow cylindrical rods, 25 nm in diameter and are composed of the protein tubulin. They occur singly, in pairs, triplets or bundles.
In addition to providing structural support, they are involved in many cellular functions like mitosis and vesicular transport. Microtubules are also part of the cilia and flagella of eukaryotic cells.
