General Information

Term

embryonic/larval pharynx

ID (Ontology)

FBbt:00001866 (Fly Anatomy)

Definition

Region of the embryonic/larval foregut between the atrium and the esophagus. It consists of a bulbous epithelial tube associated with an elaborate chitinous skeleton and musculature. The anterior edge of the pharynx is delimited ventrally by the opening of the salivary gland common duct and dorsally by the median tooth of the mouth hooks. The posterior edge is delimited by the narrowing of the foregut that marks the beginning of the esophagus.[ FlyBase:FBrf0089570 ]

Also Known As

"larval pharynx"

Comment

Bodenstein, 1950, uses the term pharynx to refer to the entire anterior portion of the larval foregut, which in this ontology is divided into the atrium (anterior) and pharynx (posterior).
