General Information
Term larval A1-7-innervating LT3/LT4 motor neuron ID (Ontology) FBbt:00110272 (Fly Anatomy)
Definition Larval LT3/LT4 motor neuron that innervates the LT3 and LT4 muscles of an abdominal 1-7 segment. It fasciculates with the SNa nerve branch and innervates muscles in the same segment as its soma (Landgraf et al., 1997; Schmid et al, 1999; Hoang and Chiba, 2001).[ FlyBase:FBrf0099344 FlyBase:FBrf0112030 FlyBase:FBrf0132289 FlyBase:FBrf0233076 ]
Also Known As "A1-7 MN-LT4" ; "A1-7 MN23/24-Ib"
