Synaptic junctions in the sinus gland of the freshwater prawn Palaemon paucidens

Cell and Tissue Research Aims and scope Submit manuscript

Summary

Two types of neurosecretory fibers, designated as Type 5 and Type 6 axons, in the sinus gland of the freshwater prawn, Palaemon, establish contact with other neurosecretory axons by means of synaptic junctions. This finding strongly supports the view that release of some neurohormones from the eyestalk may be regulated by neurosecretory neurons through synaptic transmission.
