spasmonemen.

/ˈspazməʊniːm/

Etymology: < German spasmonem (G. Entz 1892, in Math. u. Naturwissensch. Berichte aus Ungarn X. 27), < Greek σπασμός pulling, convulsion + νῆμα thread.

Zoology.

One of the three strands in the stalk of a vorticellid whose sudden contraction causes the stalk to coil tightly, withdrawing the animal from possible danger.

1901 G. N. Calkins Protozoa 179 The strand has three threads which Entz calls spasmoneme, spironeme, and axoneme.

1941 Beams & King in Calkins & Summers Protozoa in Biol. Res. ii. 94 The spasmoneme does not function like a true muscle but like a modified flagellum.

1978 Jrnl. Cell Biol. 77 358/2 Within the stalk is the contractile organelle, often referred to as the myoneme, though the term spasmoneme is preferable since recent studies indicate that the organelle is biochemically distinct from the myosin- and actin-based contractile systems.
