Smooth muscle fiber types and a novel pattern of thick filaments in the wing of the pteropod mollusc Clione limacina
Wing (parapodial) retraction in the pteropod mollusc Clione limacina is a reflex triggered by tactile stimulation. Light and transmission electron microscopy revealed three groups of smooth muscles in the wing hemocoel that participate in retraction movements: transverse, longitudinal, and dorsovent...
