Cytoskelton • With in the Cytoplasm there is a network of thin tubes and little filaments (like hairs) that act as a skeleton for the inside of the cell. Cytoskeleton • Microtubules are thin hollow tubes made up of protein. • They extend from the nucleus and attach to the other organelles to help stabilize and support everything in the cell. CytoSkeleton • Microfilaments are smaller than microtubules and are little round balls of protein all strung together like a rope. • They will contract and expand to help the cell mover or crawl. • This is what causes your muscles to contract. CytoSkeleton • Intermediate Filaments are hair like strands that anchor the nucleus and a few other organelles to the cell membrane. • It also helps give support to the cell. Cell Movement • On the outside of the cell are microtubules that act like called Cilia and Flagella. • Cillia are short and numerous • Falgela are long, but scarce. Cell Movement • Both the Cilia and the Flagella can vibrate which helps to move the cell around. • You have Cilia on the cells in your ear. When they vibrate your brain gets a signal and we hear.
