Cytoskeletal filaments are essential components of the cytoskeleton, a network that provides structural support to cells. These filaments are primarily classified into three types: microfilaments, intermediate filaments, and microtubules. Each type has distinct functions, such as maintaining cell shape, enabling movement, and facilitating intracellular transport. Microfilaments, made of actin, are involved in cell motility and shape changes. Intermediate filaments provide mechanical strength, while microtubules, composed of tubulin, play a crucial role in cell division and organization. Together, these filaments help maintain cellular integrity and enable various cellular processes.
