General Information
Term larval VL3/4 motor neuron ID (Ontology) FBbt:00001455 (Fly Anatomy)
Definition 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).[ FlyBase:FBrf0053781 FlyBase:FBrf0099344 FlyBase:FBrf0112030 FlyBase:FBrf0208790 FlyBase:FBrf0253566 ]
Also Known As"MN-VL3/4" ; "MN6/7-Ib" ; "RP3 motor neuron" (for all, see Synonyms field below)
CommentEach of the two of these neurons in A1 hemineuromeres sometimes only innervate one of VL3 or VL4 (Wang et al., 2022).
