General Information

Term

neuroblast NB7-3

ID (Ontology)

FBbt:00001426 (Fly Anatomy)

Definition

Neuroblast that delaminates in the fifth wave in the posteriormost row of the intermediate column (Schmid et al., 1999). Its primary lineage contains a motorneuron and three interneurons (Schmid et al., 1999; Karcavich and Doe, 2005). One of these cells can be found in each hemisegment from S1-A8 (Birkholz et al., 2013; Urbach et al., 2016), until it dies after producing its third GMC, during the embryonic stage (Karcavich and Doe, 2005, Lacin and Truman, 2016).[ FlyBase:FBrf0112030 FlyBase:FBrf0184104 FlyBase:FBrf0221210 FlyBase:FBrf0231327 FlyBase:FBrf0232096 ]
