A1-7 DO2 motor neuron [FBbt_00110230]
Motor neuron that innervates the internal dorsal oblique muscle 2 of larval abdominal segments A1 to A7. Its dendritic arborization occupies the lateral domain of the ventral nerve cord neuropil. It exits the ventral nerve cord via the anterior root of the intersegmental nerve and innervates the DO2 muscle with type Ib boutons. 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. Based on cell body position, the DO2 motor neuron appears to correspond to the U3 neuron (personal communication by Matthias Landgraf - FBrf0221138), however, Zarin et al. (2019) report that the DO2 motor neuron corresponds to U2.
