General Information
Term saddle ID (Ontology) FBbt:00045048 (Fly Anatomy)
Definition Synaptic neuropil domain covering the dorsal and posterior surface of the adult gnathal ganglia. It contains the antennal mechanosensory and motor center (AMMC).[ FlyBase:FBrf0212704 FlyBase:FBrf0224194 ]
Also Known As"SAD"
CommentThe saddle corresponds to the antennal mechanosensory and motor center (AMMC) of Chiang et al. (2011) and to the lateral and ventromedial periesophageal neuropils (Ito et al., 2014).
