General Information
Term larval posterior intersegmental nerve root of A1-7 ID (Ontology) FBbt:00110211 (Fly Anatomy)
Definition Posterior root of the intersegmental nerve of abdominal segments 1 to 7, through which the motor neurons of the same segment project, to innervate the muscles. The nerve connects to the neuropil at a dorsolateral position and the fascicle takes a dorsal route towards the midline, passing just below the DI fascicle, feeding into a dorsal commissure (Landgraf et al., 2003).[ FlyBase:FBrf0099344 FlyBase:FBrf0160715 ]
