PVW
The Mind of 
	a Worm

Members: PVWL, PVWR.

PVW is a set of two interneurons with cell bodies situated in the lumbar ganglia. Anteriorly directed processes enter the pre-anal ganglia via the lumbar commissures and then run alongside each other near the centre of the process bundle of the ventral cord, adjacent and ventral to the processes of PVN. The processes of PVW end somewhere in the posterior body regions, although the exact point has not been located. PVW makes a few rather small synapses in the cord, each having only a few synaptic vesicles. The main postsynaptic partners are PVT (a, b) and possibly AVD (c); there are gap junctions to PVC (d).
