General Information
Term larval DO3 motor neuron ID (Ontology) FBbt:00011548 (Fly Anatomy)
Definition Motor neuron that innervates the dorsal oblique muscle 3 (muscle 11). There are muscles referred to as dorsal oblique 3 in segments T1 to A7 (Bate, 1993).[ FlyBase:FBrf0064795 FlyBase:FBrf0099344 FlyBase:FBrf0112030 FlyBase:FBrf0208790 ]
Also Known As"MN-DO3" ; "MN11-Ib"
CommentFollowing Landgraf et al., 1997, larval motor neurons are named according to the muscle they innervate. The same caveats therefore apply regarding inference of serial homology from nomenclature as for the muscles: Following Bate (1993), larval hypodermal muscles are named for their orientation and numbered based on their order from dorsal to ventral or anterior to posterior. So, except where musculature is essentially identical between segments (as for A1-7, with a couple of exceptions for A1), serial homology should not be assumed on the basis of a shared name.
