General Information
Term larval A1-7-innervating VA1 motor neuron ID (Ontology) FBbt:00110254 (Fly Anatomy)
Definition Motor neuron that innervates the external ventral acute muscle 1 of larval abdominal segments A1 to A7. It exits the ventral nerve cord via the segmental nerve root, fasciculating with the SNc nerve branch. These neurons (at least in A1 to A4) die during metamorphosis (Banerjee et al., 2016).[ FlyBase:FBrf0099344 FlyBase:FBrf0234013 ]
Also Known As "A1-7 MN-VA1" ; "A1-7 MN26-Ib"
