General Information
Term larval LT3 motor neuron ID (Ontology) FBbt:00110267 (Fly Anatomy)
Definition Larval motor neuron of the NB3-2 lineage that innervates only lateral transverse muscle 3, via type Ib boutons (Landgraf et al., 1997; Wang et al., 2022). It arborizes in the ipsilateral neuropil, and its axon fasciculates with the ipsilateral segmental nerve, innervating a muscle of the same segment as its soma (Landgraf et al., 1997).[ FlyBase:FBrf0099344 FlyBase:FBrf0253566 ]
Also Known As "MN-LT3" ; "MN23-Ib"
Comment Many papers do not identify this neuron, but a neuron innervating only LT3 was found by Wang et al. (2022).
