General Information
Term larval VA3 motor neuron ID (Ontology) FBbt:00110258 (Fly Anatomy)
Definition Motor neuron that innervates the external ventral acute muscle 3 (muscle 29) via type Ib synapses (Zarin et al., 2019). Muscles referred to as VA3 exist in segments A1 to A7 (Bate, 1993). It exits the ventral nerve cord via the segmental nerve, fasciculating with the SNc branch (Landgraf et al., 1997). The muscle it innervates is in the same segment as its cell body (Landgraf et al., 2003).[ FlyBase:FBrf0064793 FlyBase:FBrf0099344 FlyBase:FBrf0167986 FlyBase:FBrf0244727 ]
Also Known As "MN-VA3" ; "MN29-Ib"
