WormMine: ExpressionPattern Expr3720

• Pattern: In C. elegans males, nph-4::GFP expression in the head was seen in the amphid neurons, the outer labial neurons, and a cell group that could be compatible with the male-specific CEM neurons. In the male tail, nph-4::GFP expression was seen in the lumbar and cloacal ganglia. nph-4 expression in hermaphrodites was found in ciliated amphid neurons, the outer labial neurons, and the phasmid neurons in the tail. Developmental regulation of expression for nph-4::GFP was found to be similar to nph-1, appearing at the 1.5-fold stage and lasting through adulthood.

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
