Interactions Between Conducting Systems in the Sea Anemone Calliactis Parasitica

  • I. D. McFarlane
  • A. J. Jackson


Three conducting systems have been described in sea anemones (Pantin, 1935; McFarlane, 1969a, b, 1974a; McFarlane & Lawn, 1972). The through-conducting nerve net (TCNN) excites fast and slow muscle contractions. Slow systems 1 & 2 (SS1 & SS2), both possibly non-nervous, inhibit inherent contractions of ectodermal and endodermal muscles respectively. The SS1 coordinates pedal disk detachment in Calliactis parasitica.
