AI overview
The cytoskeleton is a network of protein structures inside cells made up of microtubules, microfilaments, and intermediate filaments that gives cells their shape and organization. It matters because these structures help cells maintain their form and enable internal movement and transport within the cell.

The cytoskeleton is a complex, dynamic network of interlinking protein filaments present in the cytoplasm of all cells, including those of bacteria and archaea. In eukaryotes, it extends from the cell nucleus to the cell membrane and is composed of similar proteins in the various organisms. It is composed of three main components: microfilaments, intermediate filaments, and microtubules, and these are all capable of rapid growth and/or disassembly depending on the cell's requirements.
