The flagellar apparatus consists of the flagellar filament made of polymerized flagellin, the hook-like structure near the cell surface and a system of rings embedded in the cell enveloppe (the basal body or flagellar motor). The basal body and the hook anchor the whip-like filament to the cell surface. The flagellum is a rotating structure with switches propels the cell through a liquid medium.
