WebbThe cytoskeleton has three different types of protein elements. From narrowest to widest, they are the microfilaments (actin filaments), intermediate filaments, and microtubules. Microfilaments are often associated with myosin. They provide rigidity and shape to the cell and facilitate cellular movements. Webb29 juli 2024 · The cytoskeleton is the cell's structural framework. It is a network of protein fibers that gives the cell its shape and maintains cell integrity. The cytoskeleton also helps the cell move its components around and organize cell contents.

WebbThe submembranous cytoskeleton is a network of structural proteins, including ankyrin, fodrin and spectrin, that forms underneath the plasmalemma and interacts directly with integral membrane proteins. The formation of the submembranous cytoskeleton is correlated with the appearance of cell–cell contacts in cultured kidney cells (Fig. 5 ).
