Actin filaments, microtubules, and intermediate filaments are the three main kinds of filaments that make up the cytoskeleton. Actin filaments can be found in a cell as meshwork's or bundles of parallel fibers; they aid in the cell's structure and adhesion to the substrate.
Cytoskeleton types
Microfilaments. Out of the three different forms of cytoskeletal protein fibers, microfilaments are the thinnest. Their diameter is roughly 7 nm.
strand in the middle. Distinct forms of the intermediate filaments are produced with various different proteins.
