title: [Innervation of the cutaneous integument of pulmonary mollusks].
abstract: Cellular organization of the integumental innervation apparatus was studied in Lymnaea stagnalis and Helix vulgaris by the methods of impregnation with silver nitrate after Golgi, scanning electron microscopy, phase-contrast microscopy and by the technique of semi-thin sections. The integument of the tentacles, mouth lips, head, margins and soles of the foot was subjected to the investigation. In all the areas studied, 6 types of receptors were detected; they varied in number, diameter and form of their peripheral processes, in form of the apical surface, as well as in number, length and position of the receptory cilia. The structure of the subdermal neural plexus was demonstrated. A small number of neurons was present in the distal neural parts and in the subdermal plexus. A possible functional specialization of different receptors and morphological basis for performing peripheral dermal reflexes were discussed.
