flagellum n 1: a whip used to inflict punishment (often used for pedantic humor) [syn: {scourge}] 2: a lash-like appendage used for locomotion (e.g., in sperm cells and some bacteria and protozoa) [also: {flagella} (pl)]

(b) An appendage of the reproductive apparatus of the snail. (c) A lashlike appendage of a crustacean, esp. the terminal ortion of the antenn[ae] and the epipodite of the maxilipeds.
