Definition	Name	Synonym	Primary Identifier
A group of six equivalent cells forms a tightly constructed `valve` that links the posterior bulb of the pharynx to the anterior four cells of the intestine. These six cells comprise a small epithelial channel with a cuticular lining in continuity with the pharyngeal cuticle and link the lumen of the pharynx to the large lumen of the anterior intestine.	pharyngeal-intestinal valve	cardia	WBbt:0005767
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

Pattern	Both cgt-1::gfp and cgt-3::gfp were strongly expressed in pharyngeal muscles and in other pharyngeal cells, although their expression did not completely overlap. In addition, they showed strong expression in the pharyngeal intestinal valve (PIV), in the intestinal cells (particularly the most anterior and the most posterior), in the intestinal rectal valve (IRV), and in the three rectal gland cells (RGCs). Some cgt-3::gfp expression was also visible in head mesodermal cells.	Primary Identifier	Expr8572
Remark	Both cgt-1 and cgt-3 showed additional, non-overlapping, expression in some non-identified head cells. With the possible exception of a few amphid neurons, authors could not detect any expression of cgt-1 or cgt-3 in the nervous system. Picture: Fig. 6.
