General Information
Term larval A1-7-innervating SBM motor neuron ID (Ontology) FBbt:00110276 (Fly Anatomy)
Definition Motor neuron developing from the neuroblast NB2-4 lineage that innervates the external segment border muscle of abdominal segments 1 to 7 (Schmid et al., 1999). It exits the ventral nerve cord via the segmental nerve SNa branch and innervates the SBM muscle of the same segment with type Ib boutons (Hoang and Chiba, 2001; Zarin and Labrador, 2019).[ FlyBase:FBrf0112030 FlyBase:FBrf0132289 FlyBase:FBrf0160715 FlyBase:FBrf0167986 FlyBase:FBrf0174847 FlyBase:FBrf0208790 FlyBase:FBrf0245882 ]
Also Known As "A1-7 MN-SBM" ; "A1-7 MN8-Ib"
