General Information
Term abdominal 9 neuroblast NB5-4 ID (Ontology) FBbt:00052513 (Fly Anatomy)
Definition Neuroblast NB5-4 found in abdominal segment 9. It begins to express doublesex in the late embryo, resulting in sexually-dimorphic behavior in the larva (Birkholz et al., 2013).[ FlyBase:FBrf0221210 ]
Also Known As "A9 neuroblast 22" ; "A9 neuroblast NB5-4" ; "abdominal 9 neuroblast 22" (for all, see Synonyms field below)
Comment Appears to be two of these on each side in the larva (expressing same markers and generating similar male secondary lineage) - unclear whether this is due to division, migration or if one is a different type of neuroblast (Birkholz et al., 2013).
