part of continuous with larval abdominal intersegmental nerve larval intersegmental nerve branch ISNd of A1-7 2008-12-05T08:52:41Z fly_anatomy.ontology VFB:FBbt_00007327 ISNd could be considered a branch of ISNb, which is in turn a branch of ISN (Landgraf et al., 1997). A ventral branch of the intersegmental nerve of segments A1-7 that exits the ventral nerve cord through the anterior root of the intersegmental nerve. Its branching point is ventral to that of ISNb. It consists mostly of motorneuron axons whose soma is located in the next anterior segment, which innervate various ventral somatic muscles.
