Neural and neurosecretory control of the decapod crustacean auxiliary heart

Abstract

An auxiliary heart is found in many decapod crustaceans at the anterior end of the dorsal median artery. A brief description of the anatomy is given here, followed by an exploration of the reflex and neurosecretory control. The relationship between the activity of the main heart and auxiliary heart and the integration of the auxiliary heart with other blood pressure regulating systems of the body are discussed. © 1979 by the American Society of Zoologists.
