Physiologic Studies on the Heart of Amblema peruviana. The heart of the freshwater clam, Amblema peruviana was found to be relatively insensitive to changes in ionic concentrations, and could function in extremely dilute ionic environments. Pharmacologic studies showed a bimodal acetylcholine response, with inhibition at lower concentrations, and excitation at higher concentrations. CI- ion was found to potentiate the depressor acetylcholine response. The resting membrane potential was found to be more negative than that found in comparable marine species.
