General Information
Term tritocerebral neuroblast ID (Ontology) FBbt:00001363 (Fly Anatomy)
Definition A neuroblast located in the tritocerebrum. Most, if not all, of these have serial homology to neuroblasts found in the thoracic neuromeres (Urbach et al., 2016). There are 13 of these, of which four produce a secondary lineage (Kuert et al., 2012; Urbach et al., 2016).[ FlyBase:FBrf0089217 FlyBase:FBrf0161021 FlyBase:FBrf0220148 FlyBase:FBrf0232096 ]
Comment In the embryo, individual neuroblasts are named according to their position relative to major morphological features (cephalic furrow, invaginating foregut, dorsal and ventral midline, their relative position with respect to each other, their time of segregation and their expression of markers) (Urbach et al., 2003).
