mi·cro·tu·bule

 (mī′krō-to͞o′byo͞ol, -tyo͞o-)
n.
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.

microtubule

(ˌmaɪkrəʊˈtjuːbjuːl)
n
(Biology) biology a tubular aggregate of protein subunits that forms structures, such as the mitotic spindle or the cilia of animal cells or of protozoans, in which the protein interacts with other proteins to generate various cellular movements

mi·cro·tu·bule

(mī′krō-to͞o′byo͞ol)
Any of the tube-shaped structures that help cells maintain their shape and assist in forming the cell spindle during cell division. Microtubules are found in the cytoplasm of the cells of all organisms except bacteria.
