AMRP neurons in the abdominal ganglion.A1,In situ hybridization of dorsal surface. A2, Immunocytochemistry of dorsal surface.A3, Drawing of the AMRP neurons on the dorsal abdominal ganglion. B1,In situ hybridization of ventral surface. B2, Immunocytochemistry of ventral surface. Inset is the same region asarrow, partially desheathed bag cells from an adult animal showing dense immunopositive innervation of the sheath overlying the bag cells, but not the bag cells themselves. B3,Drawing of the AMRP neurons on the ventral abdominal ganglion.LC, Left pleuroabdominal connective; RC,right pleuroabdominal connective; VN, vulvar nerve;BN, branchial nerve; STN, spermathecal nerve; PN, pericardial nerve; GN, genital nerve; SN, siphon nerve. Scale bar: A1,500 μm (same in all panels, includinginset).
