axostyle
An elongate supporting rod or tubule that runs the length of certain flagellate protozoans, frequently projecting out of the posterior end. Single or multiple, filamentous or rigid, they vary with the species but serve as an endoskeletal framework and may function in locomotion as well. [axo- + G. stylos, pillar]
