The cytoskeleton itself is made up of microtubules, the only difference being size and function. Microtubule is solely support of the physical arrangement of the cytoskeleton, and the cytoskeleton protects the site from outside invaders or forces.
Microtubules are mainly responsible for cell movement, contraction of the muscles, cyclosis in a plant and moving of amoeboid. While, actin filaments are the ones that transports vesicles, handling chromosomes in mitosis and even has a role in the cell shaping process.
Microfilaments are tiny rods of action proteins that form meshworks or bundles. Microtubules are long slender tubes with diameters two or three times those of microfilaments

The cytoskeleton is composed of Actin filaments, microtubules and intermediate filaments. Actin is essential in resistance to and distribution of physical stresses and for movement in some Cells such as immune Cells. It is also important for orientation in Cells such as columnar epithelial Cells. Actin combines with Myosin to produce Motile Elements - such as - Microtubules are used to transport materials and organelles around the Cell. Microtubules are also essential in the separation of sister chromatids during anaphase in Cells that undergo Cell division. Intermediate filaments are more complex in structure than Actin and MTs and far more varied but are still dynamic. IFs are important in the interactions between Cells to make up tissues and organs. Because of their varied functions they are divided into classes (Types I to V).

A dynamic structure that stabilizes cells lacking a cell wall (=animal cells). It consists out of microtubules, intermediate filaments and actin filaments.

The cytoskeleton is a network of microfilaments and microtubules that provides shape and coherence to the cell. It is mainly composed of proteins.
Cytoskeletal filaments are made up of actin, intermediate filaments that contain 70 different proteins coupled with microtubules with tubulin as the basic subunit.
(1)Microfilaments (also know as actin filaments) are actually only one type of filament in the eukaryotic cytoskeleton. The two other filaments are (2)intermediate filaments and (3)microtubules.

The cytoskeleton is a network of fibers that maintains the shape of cells. The three types of fibers are actin filaments, microtubules, and intermediate filaments. Actin filaments are long fibers composed of two protein chains. They are responsible for cellular movements, such as contraction, crawling, "pinching" during division, and formation of cellular extensions. Microtubules are hollow tubes composed of a ring of thirteen protein filaments. They are responsible for moving materials within the cell. Intermediate filaments are tough, fibrous protein molecules structured in an overlapping arrangement. They are intermediate in size when compared to actin filaments and microtubules, and provide structural stability to cells.Read more: what-are-the-three-types-of-fibers-found-in-the-cytoskeleton-of-eukaryotic-cells
