WormMine: ExpressionPattern Expr7471

• Pattern: Expression observed from early embryo to adult. Early and mid embryo show expression in several cells. Strongest expression is in late embryos and L1 in dorsal and ventral nerve cords and three pairs of head nerves, one pair with processes to head tip. After L1 dorsal nerve cord and one pair of head nerves show expression. Weak expression seen in two pairs of tail nerves. Expression sometimes seen in structures at head tip (possibly the arcade cells or head hypodermis). Possibly artifactual expression seen in body wall muscles, head muscles and intestine.

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
a large process bundle that runs along the vental mid-line extending from the ventral region of the nerve ring.	ventral nerve cord	ventral cord	WBbt:0005829
Longitudinal bands of muscle cells surrounding animal body, with one band running in each quadrant of the body, regulated contraction and relaxation of these muscles cause locomotion.	body wall musculature	body muscle	WBbt:0005813
