Neurons in the cephalic region of A. suum. (a) Diagram of the head ganglia of A. suum modified from Goldschmidt.56 The worm has been cut longitudinally near the DC and opened flat. Neuronal cell bodies and commissural processes are shown. (b) Neurons expressing AF11 in A. suum. Diagram shows the cell bodies of AVKR (green), AVKL (red) of the VG, and ALA (blue) of the DG. The AVKs each send a process anteriorly toward the midline, turn ipsilaterally into the NR, traverse the NR, and then proceed posteriorly down the contralateral side of the VC. The ALA sends two processes anteriorly into the NR, where they diverge. One goes left, enters the LLL and travels posteriorly; the other goes right and travels down the RLL. (c) Manually dissected AVKR neuron for direct MS analysis. Nerve ring (NR), ventral ganglion (VG), dorsal ganglion (DG),lateral ganglia (LG), retrovesicular ganglion (RVG), left lateral line (LLL), right lateral line (RLL), ventral nerve cord (VC), dorsal nerve cord (DC), deirid commissures (DeC), amphidial commissures (AC).
