Abstract
The isolated columellar muscle of Helix aspersa is caused to contract by addition to it of ephedrine, adrenaline, veratrine, Ba++ and acetylcholine. Adrenaline and acetylcholine are active in concentrations of 10-6 or less. The action of acetylcholine is potentiated by eserine and abolished by atropine, but not by curare, indicating a muscarinic cholinergic innervation of this muscle. The heart muscle is sensitive to sympathornimetic substances only. The muscle of the alimentary canal is insensitive to drugs.Keywords
