Abstract: 
The central heart of the coleoid cephalopod, Sepia officinalis, was studied using acetylcholinesterase and fluoresence histochemistry. Using histo- and cytochemical reactions, acetylcholinesterase was localized in the axolemma and axoplasm of specific cardiac nerve fibres, as well as in the sarcolemma and within the sarcotubular system of the muscle cells. Butyrylcholinesterase exhibited a different distribution, being found only in the luminal trabecular muscle layer. Glyoxylic-acid-induced fluorescence indicated the presence of catecholamines (emission maximum, 470 nm) in cardiac nerve axons. These histochemical findings support the hypothesis that noradrenaline and/or dopamine and acetylcholine act antagonistically as natural transmitters. Fluorophores indicating the presence of serotonin were not observed. The present results are discussed in the light of previous pharmacological findings.
