- excretory cell
H-shaped cell associated with the excretory system, largest cell in C. elegans.
- 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.
- 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.
- SM lineage cell
A cell that is a sex myoblast or is a lineal descendant of a sex myoblast.
- neuroblast
A blast cell from which a neuron develops.
