Microtubules are one type of cytoskeletons. Cytoskeletons are important in animal cells to give the cell support and shape, it also helps anchor many of the organelles in the cell to its position. Cytoskeletons also work with motor proteins to give the cell and organelles inside the cell mobility.
Microtubules are hollow rods made from globular proteins called tubulin. Other cytoskeletons; the microfilaments (actin filaments) and intermediate filaments are also made of proteins.
Centrioles are composed of 9 sets of triplet microtubules, arranged in a ring. In animal cells a pair of centrioles are found in the centrosome area near the nucleus. These microtubules in the centrioles separate chromosomes during cell division.
