a single, H-shaped cell which lies just above the anus and connects the roof of the anal canal to the dorsal bodywall; its contractions act to increase the size of the anal opening by lifting the roof of the rectum and hence facilitate expulsion of intestinal contents. |

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. |

|
ganglion lies beside the nerve ring in the head, just anterior of the retrovesicular ganglion. It contains about 20 interneuron and motorneuron cell bodies that all send their neuronal processes into the ring. The cell bodies are divided into two groups by the intrusion of the excretory duct and canal. The cells are bounded by a basal lamina which physically separates them from the lateral ganglion even though they are adjacent to one another. |
