The cytoskeleton is a complex, dynamic network of protein filaments found inside the cytoplasm of cells, providing essential structural support and maintaining cell shape. This intricate system is composed of three primary types of polymers: actin filaments, which are crucial for muscle contraction and cell crawling; microtubules, which function in maintaining internal organization and guiding organelle movement; and intermediate filaments, which offer tensile strength and mechanical resilience. These components interact dynamically to enable cell motility, facilitate the intracellular transport of vesicles, and anchor cellular components, thereby playing fundamental roles in processes such as cell division and overall tissue integrity.
