/ˈmaɪoʊˌnim/

Origin: A borrowing from German. Etymon: German Myonem.

Etymology: < German Myonem (O. Bütschli H. G. Bronn's Klassen u. Ordnungen des Thier-Reichs: Protozoa (1888) III. 1295) < myo- myo- comb. form + ancient Greek νῆμα thread (see nemato- comb. form; compare -nema suffix).

Biology.

Any of the minute contractile filaments found in the cytoplasm of many protozoans.
