General Information
Term larval VL3/4 motor neuron of abdominal 1 neuromere ID (Ontology) FBbt:00002217 (Fly Anatomy)
Definition Larval VL3/4 motor neuron with its soma in the abdominal 1 neuromere. It crosses the segment boundary and innervates musculature in the abdominal 2 segment.
Also Known As "A1 MN6/7-Ib" ; "A1 RP3 MN" ; "A1 VL3/4 MN" (for all, see Synonyms field below)
Comment Two of these were found by Wang et al. (2022), unlike in other segments. Based on soma location and shared features with other VL3/4 neurons, they are both also thought to arise from NB3-1.
