PHC is a set of two neurons with cell bodies situated in the lumbar ganglia. Posteriorly
directed processes run from the cell bodies into the tails pike (e) running alongside the processes
of PLM and PLN. The disposition of these processes suggests that they may be sensory
dendrites. Anteriorly directed processes leave the cell body and enter the pre-anal ganglion via
the lumbar commissures and run for a short distance near the middle of the neuropile before
ending. The main synaptic output is to DVA (c), PVC (a) and DA9 (a). There are gap
junctions to itself (d), VA12 and DA9.
