The cytoskeleton is a dynamic network of protein filaments and tubules in the cytoplasm of many living cells, giving them shape and coherence. It is composed of three main types of filaments: microfilaments, intermediate filaments, and microtubules. Microfilaments, also known as actin filaments, are thin, flexible rods that play a role in cell shape, muscle contraction, and cell movement. Intermediate filaments are tougher and more stable, providing mechanical strength to cells and tissues. Microtubules are hollow tubes that serve as tracks for intracellular transport and are essential for cell division and maintaining cell shape.
The cytoskeleton is involved in a wide range of cellular processes. It anchors organelles, provides mechanical
The structure and function of the cytoskeleton are constantly regulated by various proteins that promote or
