title: The structure of Archiannelid Dinophilus gyrociliatus ventral nerve cords.
abstract: Dinophilus gyrociliatus is a typical representative of the synthetic group Archiannelida. Here we describe the structure of Dinophilus young adults ventral nerve cords. Five nerve cords, irregular commissures and intersegmental nerves are revealed by tubulin and FMRFamide immunostaining. 5-HT-stainning marks the complex varicose nerve plexus with numerous irregularly distributed small perikarya. Four nerve cords and solitary cell bodies occur after clyoxylic-induced reaction for catecholamines visualization. Altogether, our results indicated that morphology of Dinophilus ventral nerve cords differs from the Polychaetes archetype in many respects.
