Myoneural Junctions in the Connective Tissue Sheath of a Molluscan Ganglion

Nature volume 219, pages 1371–1372 (1968)Cite this article

Abstract

NERVE and muscle cells have been described in the connective tissue sheath which surrounds the ganglia and peripheral nerves of the molluscan nervous system1,2. In Aplysia no morphological evidence has been obtained for functional contact between the two types of cells1. In the investigation reported here, an electron microscopic analysis of the fine structure of the osphradial ganglion of the freshwater pulmonate snail, Planorbarius corneus L., showed the presence of numerous myoneural junctions in the ganglion sheath. The junctions are similar to those described in the heart of Achatina fulica3 and the penis retractor of Helix pomatia4—two other pulmonate snails.
