General Information
Term flange ID (Ontology) FBbt:00045050 (Fly Anatomy)
Definition A small, bilaterally paired, triangular synaptic neuropil domain that lies above the anterior end of the saddle, on both sides of the esophagus (Ito et al., 2014). It lies at the root of the median bundle, behind the prow (Ito et al., 2014). It forms the dorsal part of the adult tritocerebrum, developing from the centromedial and dorsal domains of the larval tritocerebrum (Hartenstein et al., 2018).[ FlyBase:FBrf0224194 FlyBase:FBrf0237252 ]
Also Known As "dorsal tritocerebrum" ; "FLA" ; "TRd"
Comment The flange corresponds to the dorsoposterior part of the subesophageal ganglion (SOG) of Chiang et al. (2011) and to part of the anterior periesophageal neuropils (Ito et al., 2014).
