The cytoskeleton is a network of protein fibers within the cytoplasm that provides structural support, facilitates cell movement, and aids in the transport of materials within the cell. It is composed of three main types of fibers:
Microfilaments: These are thin fibers made of actin that are involved in cell movement and shape maintenance. Intermediate Filaments: These fibers provide mechanical strength to cells and help maintain their integrity. Microtubules: These are hollow tubes made of tubulin that play a crucial role in cell division, intracellular transport, and maintaining cell shape.
