Now, the cytoskeleton is a network of protein fibers that permeate all of the cell and it basically functions to give the cell structure as well as motility. So in a way we can imagine that the cytoskeleton is like the bone structure of our body body. It gives the cell its structure, it gives the cell its shape. It also gives the cell the ability to resist different types of forces and pressures. But the cytoskeleton is more than that. Not only is it a scaffolding system, it's also a highway system.
