Microtubules are filamentous intracellular structures that are responsible for various kinds of movements in all eukaryotic cells. Microtubules are involved in nucleic and cell division, organization of intracellular structure, and intracellular transport, as well as ciliary and flagellar motility.icrotubules form a framework for structures such as the spindle apparatus that appears during cell division, or the whiplike organelles known as cilia and flagella. Cilia and flagella are the most well-studied models for microtubule structure and assembly, and are often used by textbooks to introduce microtubules.
1. The cytoskeleton is the cytoplasmic structure that supports the cell, maintains its shape and holds or moves cell organelles. It is made of an extensive network of fibers dispersed in the cytoplasm and anchored in the plasma membrane. Its components are microtubules, microfilaments and intermediate filaments.. Microtubules are made of consecutive dimers of the protein tubulin (each dimer contains an alpha and a beta tubulin). Microtubules play a role in cell division; they are components of cilia and flagella and they also form centrioles.
