 (mī′krō-to͞o′byo͞ol, -tyo͞o-)
Any of the cylindrical hollow tubulin-containing structures that are found in the cytoplasm, cilia, and flagella of eukaryotic cells and are involved in determining cell shape and structure and directing the movement of organelles and chromosomes. Microtubules, along with microfilaments and intermediate filaments, make up a cell's cytoskeleton.
