General Information
Term larval VO1 motor neuron ID (Ontology) FBbt:00001456 (Fly Anatomy)
Definition Motor neuron of the 3-1 lineage with a large cell body located adjacent to that of RP1 (Schmid et al., 1999). It innervates the contralateral ventral oblique muscle 1 (VO1; muscle 30) (Zarin et al., 2019).[ FlyBase:FBrf0053781 FlyBase:FBrf0099344 FlyBase:FBrf0112030 FlyBase:FBrf0244727 ]
Also Known As "MN-VO1" ; "MN30-Ib" ; "RP4 motor neuron"
