- seam cell
a group of hypodermal cells that lie along the apical midline of the hypodermis, at the extreme left and right sides between nose and tail
- excretory canal
Four processes (canals) of the excretory canal cell each contain a central collecting lumen which feeds to a central lumenal canal in the cell body; the central canal forms a specialized membrane to release fluids into the excretory duct. These five canals form a continuous H-shaped channel which extends almost the full length of the body, generally in contact with the lateral hypodermis and the pseudocoelom.
- hyp8
Tail ventral hypodermis, 8th hypodermis cell
- hyp9
Tail ventral hypodermis, 9th hypodermis cell
- 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.
