The cytoskeleton is a cellular organelle that provides structure to the cell.  The cytoskeleton shapes and supports the cell with a network of microtubules.  Microtubules in the cytoskeleton are arranged throughout the cytoplasm as beams holding the shape of the cell.


Humans have a skeletal structure made of bone that holds the contents of the body together.  In the same way that human bodies are held together by a skeleton, cells are held together by a cytoskeleton.
