spasmoneme Zool.|ˈspæzməʊniːm|
[ad. G. spasmonem (G. Entz 1892, in Math. und naturwissensch. Berichte aus Ungarn X. 27), f. Gr. σπασµό-ς pulling, convulsion + νῆµ-α thread.]
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[see axoneme]. 1941Beams & King in Calkins & Summers Protozoa in Biol. Res. ii. 94 The spasmoneme does not function like a true muscle but like a modified flagellum. 1978Jrnl. Cell Biol. LXXVII. 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. |
