has characteristic synapsed_via_type_Ib_bouton_to sends synaptic output to cell ventral longitudinal muscle cell RP neuron larval VL3/4 motor neuron RP3 neuron RP3 motor neuron VFB:FBbt_00001455 fly_anatomy.ontology Larval motor neuron of the NB3-1 lineage that innervates ventral longitudinal muscles 3 and/or 4 (Schmid et al., 1999, Mauss et al., 2009; Wang et al., 2022). In each A1 hemineuromere, there are two of these cells, which may innervate one or both muscles, in other hemineuromeres, these is only one of these cells, which innervates both muscles (Wang et al., 2022). FBbt:00001455 Each of the two of these neurons in A1 hemineuromeres sometimes only innervate one of VL3 or VL4 (Wang et al., 2022).
