A1-7 DO1 motor neuron [FBbt_00002303]
U1 neuron of A1-7. It innervates dorsal oblique muscle 1 (DO1). Its dendritic arborization occupies the lateral domains of the ventral nerve cord neuropil. It exits the ventral nerve cord via the anterior root of the intersegmental nerve and innervates the DO1 muscle of the next posterior segment with type Ib boutons (Landgraf et al., 1997; Hoang and Chiba, 2001; 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. Based on cell body position, the DO1 motor neuron corresponds to the U1 neuron (personal communication by Matthias Landgraf - FBrf0221138).
