The cytoskeleton is a network of fibres extending through the cytoplasm. It gives mechanical support and maintains cell shape and is critical for animal cells, as they contain no cell wall. it is stabilised by balanced opposing forces. function include providing anchorage for organelles and cytosolic enzyme molecules, providing support and enabling motility. motility requires interactions with motor proteins, and includes bending of flagella, cytoplasmic streaming, muscle cell contraction, movement of vesicles and organelles, and movement of chromosomes during cell division. It is easily able to dismantle and resemble, and is also involved in regulating activities in response to stimuli, It is made of microtubules, microfilaments and intermediate filaments.
