General Information
Term neuroblast NB5-3 ID (Ontology) FBbt:00001390 (Fly Anatomy)
Definition Neuroblast that delaminates at S1 and generates an SNa motorneuron and intersegmental interneurons (Schmid et al., 1999). In the embryo, one of these cells can be found in each hemisegment from S1-A8 (Birkholz et al., 2013; Urbach et al., 2016). In the larva, it resumes proliferation in at least all thoracic segments and A1-A7 (Lacin and Truman, 2016). The neurons that develop from this neuroblast after larval hatching form postembryonic lineage 5 (Lacin and Truman, 2016).[ FlyBase:FBrf0112030 FlyBase:FBrf0221210 FlyBase:FBrf0228122 FlyBase:FBrf0231327 FlyBase:FBrf0232096 ]
Also Known As"lineage 5 neuroblast" ; "lineage NB5-3 neuroblast" ; "NB 5" (for all, see Synonyms field below)
CommentThis is equivalent to the 'ventrolateral neuroblast' of Truman and Bate (1988) - FBrf0047815, due to existence in A2-7 and its relatively lateral location (Lacin and Truman, 2016). Lacin and Truman (2016) do not show data for neuromeres posterior to A7.
