WormMine: ExpressionPattern Expr7537

• Pattern: The expression in early and comma stage embryos is mostly anterior and ventral. From late embryo to adult, expression is seen in many tissues but most strongly in the pharynx and muscles of the body wall, head, rectum and vulva. Other tissues showing expression include the intestine, excretory cell, seam cells, dorsal and ventral nerve cord and other nerves in the head.

Definition	Name	Synonym	Primary Identifier
A chain of very large cuboidal cells forming a wide central lumen in which food arrives from the posterior pharynx, is digested, and from which waste products proceed to the rectum. Intestinal rings form in groups of two and four cells surrounding the common lumen; thus the epithelium is only one cell deep at any point, with neighboring cells firmly secured to their neighbors by apical adherens junctions. These cells have very large nuclei and many large vacuoles, yolk granules, and other inclusions; the latter increase in number and electron density as the animal ages.	intestine	gut	WBbt:0005772

the feeding organ, a neuro-muscular pump in the head of the animal, used to ingest food, bacteria suspended in liquid, filter them out, grind them up and transport posteriorly into the instestine.	pharynx	esophagus	WBbt:0003681
neuron with its cell body situated in the head, excluding the pharynx.	head neuron		WBbt:0006751
body wall muscle in the head, including first eight cells of each muscle quadrants which are innervated by nerve ring neurons.	head muscle	head body wall muscle	WBbt:0006761
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.	anal depressor muscle	dilator muscle	WBbt:0004292
