Abstrakt: Abstract Using the method of the anterograde dextran tetramethylrhodamin transport, there is obtained the topographic picture of branching of inferior cervical nerve axons on fibers of the dorsal longitudinal muscle in Lymnaea stagnalis (L.). Using the retrograde staining, the neuronal bodies sending their processes into this nerve are marked. Manifestations of asymmetry in distribution of neurons stained through the right and left nerves are described. The electron microscopic studies have shown that the main number of the inferior cervical nerve axons is represented by thin fibers presumably belonging to the sensory cells. A part of the nerve fibers and their endings show imunoreactivity to serotonin and acetylcholine. The serotoninergic fibers predominate quantitatively over the cholinergic ones and account for a half of the fibers stained with dextran. A possible functional role of the serotoninergic and cholinergic innervation of the dorsal longitudinal muscle in Lymnaea stagnalis is discussed. [ABSTRACT FROM AUTHOR]
