General Information
Term pseudotrachea ID (Ontology) FBbt:00004164 (Fly Anatomy)
Definition Open channel that extends from the dorsal medial region of the labellum, pointing slightly around the outside of each half of the labellum. The pseudotrachea is kept open by narrow, somewhat variably shaped, transverse, sclerotised bands, the ends of which are free from the derm. There are 6 of these per palpus, conducting food to the tip of the labrum.[ FlyBase:FBrf0007734 FlyBase:FBrf0033866 ]
Also Known As "pseudotracheal ridge" ; "pseudotracheal row"
