Function: ELH acts as a neurotransmitter locally, upon neurons of the abdominal ganglion and as a hormone by diffusing into the circulating hemolymph and modulating the activity of other organs. It specifically causes contraction of smooth muscle in the ovotestis and expulsion of the egg string.; Alpha-BCP decreases the activity of a cluster of neurons in the left upper quadrant of the abdominal ganglion.; Beta-BCP specifically excites 2 neurons, L1 and R1, in the abdominal ganglion.
