Chap VII- Cytoskeleton_2026_English

“The cytoskeleton is a dynamic network of protein filaments that provides structural support, maintains cell shape, and enables intracellular transport and cell motility. It is composed of three main components—microfilaments (actin), intermediate filaments, and microtubules—each playing specific roles in mechanical stability, organelle positioning, and cellular dynamics. Beyond its structural function, the cytoskeleton is essential for processes such as cell division, vesicular trafficking, and signal transduction.”
