cytoskeleton

a network of fibres necessary for shape and stability of the cell

microfilaments microtubules intermediate

supports the cell’s organelles, keeping them in position strengthen the cell maintain the cell’s shape responsible for movement of materials within the cell proteins for movement of materials within the cell proteins of cytoskeleton can also cause the cell to move

small solid strands each one is around 7nm diameter protein = actin

responsible for cell movement and cell contraction during cytokinesis involved in phagocytosis

act as tracks for the movement of organelles around the cel make up spindle fibres, centrioles, cilia and flagella

tiny proteins cylinders - straight and hollow around 18-30 nm in diameter

accomplished by cilia and undulipodia

average 10nm diameter

give mechanical strength to cells and help maintain their integrity

molecular motors that use the cytoskeleton to move along the cytoplasm of a cell

myosin, allows muscle contraction when it interacts with actin

dynein , allows cilia/flagella movement when it interacts with tubulin kinesin, move vesicles when interacts with tubulin

cause male infertility and also lead to respiratory tract and sinus problems
