The left and right lumbar ganglia lie behind the pre-anal ganglion in the tail, in lateral positions. Each contains 12 neuron cell bodies that send most of their neuronal processes into the ventral nerve cord via lumbar commissures and the pre-anal ganglion. There is no local neuropil in these ganglia in the hermaphrodite, instead they form most synapses in the pre-anal ganglion. Most lumbar neurons have sensory functions. In the adult male tail, these two ganglia gain many additional neurons and have some local neuropil. The lumbar neurons lie in close association with the lateral hypodermis, and most are posterior to the anus.

The processes of ADF run near the outside surface and posterior face of the ring, in close association with those of AIZ. They meet at the dorsal mid-line and terminate; there is a gap junction at the point or contact. The main synaptic output is to RIA and AIZ; there are also synapses to SMB, AUA and RIR, usually in dyadic combinations with RIA or AIZ. AWB synapses onto ADF in several places, and there are gap junctions to RIH, ADA and AIA.
