  • Title: Novel triplet of flexor muscles in the posterior tentacles of the snail, Helix pomatia.
    Author: Hernádi L, Teyke T.
    Journal: Acta Biol Hung; 2012; 63 Suppl 2():123-8. PubMed ID: 22776484.
    Abstract:
    The anatomy of three novel flexor muscles in the posterior tentacles of Helix pomatia is described. The muscles originate from the ventral side of the sensory pad and are anchored at different sites in the base of the tentacle stem. The muscles span the tentacle and always take the length of the stem which depends on the rate of tentacle protrusion indicating that the muscles are both contractile and extremely stretchable. The three anchoring points at the base of the stem determine three space axes along which the contraction of a muscle or the synchronous contraction of the muscles can move the tentacle in space.
