A |network |of |fibers |that |holds |the |cell |together, |helps |the |cell |to |keep |its |shape, |and |aids |in |
movement
Microfiliments |and |microtubules
support |the |cytoplasm |and |help |move |substances |and |organelles |within |the |cytoplasm
intermediate |filaments
Threadlike |proteins |in |the |cell's |cytoskeleton |that |are |roughly |twice |as |thick |as |microfilaments
Microvilli
