General Information
Term larval VO2 motor neuron ID (Ontology) FBbt:00001452 (Fly Anatomy)
Definition A motor neuron that develops from neuroblast NB3-1 and whose large cell body is located between the anterior and posterior commissures at the dorsal surface of the CNS (Schmid et al., 1999). It innervates the ventral oblique muscle 2 (muscle 14) in abdominal segments (Zarin et al., 2019).[ FlyBase:FBrf0047653 FlyBase:FBrf0053781 FlyBase:FBrf0099344 FlyBase:FBrf0244727 ]
Also Known As"MN-VO2" ; "MN14-Ib" ; "RP1 motor neuron" (for all, see Synonyms field below)
