Emerging from the soma are the dendrites and axons. The Cytoskeleton The Cytoskeleton is a tiny network of tubules that support the cell’s structure and drive cellular movement Microtubules provide support for cell shape, help move organelles through the cytoplasm, and play a special role in cell division by forming centrioles 25.
