A1-7 VO3 motor neuron [FBbt_00110284]

Motor neuron that develops from the neuroblast NB4-2 lineage. It innervates the internal ventral oblique muscle 3 of larval abdominal segments A1 to A7. Its dendritic arborization occupies the medial domain of the ventral nerve cord neuropil. It exits the ventral nerve cord via the anterior root of the intersegmental nerve, fasciculating with the ISNb nerve branch and innervates the VO3 muscle with type Ib boutons. These neurons (at least in A1 to A4) die during metamorphosis (Banerjee et al., 2016). There is little or no published literature specifically on innervation in A1 and so where equivalent muscles are present between A1 and A2-7 (Landgraf et al., 1997; Schmid et al., 1999), we infer A1 motor neuron innervation patterns from those of A2-7.
