The autonomic control of the teleost heart Jampolsky, Michael
In adult goldfish (Carassius auratus), embryos of the herring (Clupea pallasii), and alevins of the sockeye salmon (Oncorhynchus nerka), the heart is inhibited by acetylcholine but shows no response to adrenalin. The findings are in agreement with previous investigations on the adult teleost but contrary to the condition described for the embryo Fundulus. It is concluded that the teleost heart lacks a sympathetic innervation, and that the myocardial cells are unresponsive to adrenalin at all ages.
