Expression Pattern :

Pattern  dgn-1 is expressed in lumbar ganglion neurons by the comma stage of embryogenesis, just before the beginning of lumbar axogenesis. Embryonic expression of dgn-1 in lumbar neurons is transient, although residual expression can be seen in some lumbar neurons in earlylarvae, by which time embryonic stage axon extension has concluded.

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. lumbar ganglion lumbar lateral ganglia WBbt:0005830
