General Information
Term dorsopharyngeal organ ID (Ontology) FBbt:00002652 (Fly Anatomy)
Definition Sensillum of the larval head that is located proximal to the dorsal pharyngeal sense organ along the labral nerve (Campos-Ortega and Hartenstein, 1997; Gendre et al., 2004). It is innervated by 5 neurons (Gendre et al., 2004; Stewart et al., 2015).[ FlyBase:FBrf0075072 FlyBase:FBrf0089570 FlyBase:FBrf0167539 FlyBase:FBrf0228093 ]
