E lineage cell

A cell that is the E blast cell or is a lineal descendant of E.

E nucleus

nucleus of pedigree E

excretory cell

H-shaped cell associated with the excretory system, largest cell in C. elegans.

vulE

adult vulval toroid cell, E, formed by fusion of precursors of lineage names P6.paal, P6.paar, P6.pppl and P6.pppr.

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.

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.
