The primary function of a cell's cytoskeleton is to maintain its shape, provide structural support, and facilitate cellular movement. Comprising networks of proteins such as microfilaments, intermediate filaments, and microtubules, the cytoskeleton also plays roles in cell division, intracellular transport, and the spatial organization of cellular components. Additionally, it helps cells respond to external stimuli, allowing for changes in shape and motility. A well-functioning cytoskeleton is essential for overall cell health, and its dysfunction can lead to various diseases and cellular malfunctions.
