[Peptidergic and monoaminergic innervation of the gonads in the holothurian Cucumaria japonica].
In the holothurian gonad structure of the peptidergic and monoaminergic systems has been described. Axons of their cells form tissue and hemal terminals. Epithelial cells and smooth myocytes of the gonadal wall get direct innervation, having contacts with the axonal terminals that are separated by the cleft 50-75 nm in the diameter. It is possible that neuropeptides and biogenic monoamines are transported to the germ and follicular cells of the germinative gonadal zone via hemolymph of the hemal sinus.
