General Information
Term labellar gland ID (Ontology) FBbt:00003124 (Fly Anatomy)
Definition Pyriform group of cells, consisting of about seven large epithelial cells. It surrounds an irregular lumen that opens medially, through a short small-celled duct, in close proximity to the tip of the labrum. A thin basement membrane surrounds the gland externally and a thin intima lines the lumen. There are two of these, one on each side of the labellum lobes.[ FlyBase:FBrf0186027 ]
