Evidence for serotonin (5-hydroxytryptamine) as transmitter in the penis retractor muscle ofHelix pomatia L.

  • R. W. Wabnitz

Microchromatography of dansylated substances was used to estimate the serotonin content of the penis retractor muscle (PRM) ofHelix pomatia. Pharmacological data in connection with the biochemical results suggest that 5-HT plays a role in the regulation of the mechanical activity of the PRM.
