General Information
Term neuroblast NB2-2 ID (Ontology) FBbt:00001385 (Fly Anatomy)
Definition Neuroblast that delaminates at S2 and generates three to four primary motorneurons that innervate anterior lateral muscles via the SNa and a large number of interneurons (Schmid et al., 1999). In the embryo, one of these cells can be found in each hemisegment from S1-A10 (Birkholz et al., 2013; Urbach et al., 2016). In the larva, it resumes proliferation in all thoracic segments (Lacin and Truman, 2016). The neurons that develop from this neuroblast after larval hatching form postembryonic lineage 10 (Lacin and Truman, 2016).[ FlyBase:FBrf0055900 FlyBase:FBrf0084809 FlyBase:FBrf0112030 FlyBase:FBrf0221210 FlyBase:FBrf0228122 FlyBase:FBrf0231327 FlyBase:FBrf0232096 ]
Also Known As "lineage 10 neuroblast" ; "neuroblast 10"
Comment Originally referred to as NB2-3 by Doe (1992), this was renamed to NB2-2 by Broadus et al. (1995) to keep the names of row 2 neuroblasts consistent with their position in Schistocerca.
