hyp7) and a series of programmed cell deaths. In addition, the Pn.p daughters of P3 through P8 lineages persist without fusing into the

It contains 3 neuron cell bodies (DVA, DVB and DVC) that send their neuronal processes into the ventral nerve cord via dorso-rectal commissures that encircle the anus. The ganglion contains no local neuropil in the hermaphrodite. In the adult male tail, this ganglion gains additional neurons and some local neuropil.

lumbar ganglion
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.
ALN
Neuron class of two neurons with cell bodies situated in the lumbar ganglion, send processes anteriorly, which eventually enter the nerve ring; they also have posteriorly directed processes that run into the tailspike.
lateral ganglion
The left and right lateral ganglia lie beside the nerve ring in the head. They each contain about (30) neuron cell bodies and send their neuronal processes into the ring at its posterior margin either laterally or ventrally via the amphid commissures and ventral ganglion, but form no local neuropil separate from the nerve ring. The lateral ganglia are in close contact with the lateral hypodermal cords.
