A1-7 ventral motor neuron [FBbt_00002231]
Motor neuron that innervates the ventral oblique muscles VO1, 2, 4 and 5 and ventral longitudinal muscles VL1-4 of larval abdominal segments A1 to A7 via type Is boutons (Hoang and Chiba, 2001; Mauss et al., 2009). It exits the ventral nerve cord via the anterior root of the intersegmental nerve, fasciculating with the ISNb branch, and innervates muscles in the next posterior segment to its soma (Zarin and Labrador, 2019). 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.
