(2007) report that labral nerve projections pass through area 2 and into area 1 of the subesophageal ganglion. In the majority of cases they then target the contralateral area 2. An exception to this is one DPS fiber (which labels with Gr2a-GAL4) which targets inside area 4. lrso labral sense organ dps dorsal group of pharyngeal sensilla epiphysial sense organ pharyngeal sensilla D1-D6 dorsal pharyngeal sensilla DPS Paired compound sense organ of the larval labral segment (Campos-Ortega and Hartenstein, 1997). It consists of 6 sensilla in the dorsal larval pharynx: one tri-dendritic, 2 bi-dendritic and 3 mono-dendritic (Campos-Ortega and Hartenstein, 1997). Projections generally, though not exclusively, target the contralateral subesophageal ganglion area 1 (Colomb et al., 2007). fly_anatomy.ontology FBbt:00007281 epiphysis
