- excretory cell
H-shaped cell associated with the excretory system, largest cell in C. elegans.
- anal depressor muscle
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.
- C lineage cell
A cell that is the C blast cell or is a lineal descendant of C.
- 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.
- SPC
Neuron class of two male-specific spicule neuron type C.
- PCC
Neuron class of two male-specific post cloacal sensilla neuron type C.
- PHDL
The left PHD neuron of the pair of bilateral PHD neurons in a male C. elegans animal.
- PHDR
The right PHD neuron of the pair of bilateral PHD neurons in a male C. elegans animal.
