General Information
Term larval intersegmental nerve branch ISNd of A1-7 ID (Ontology) FBbt:00007327 (Fly Anatomy)
Definition 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.[ FlyBase:FBrf0089570 FlyBase:FBrf0099344 FlyBase:FBrf0193012 ]
Also Known As "SNd"
Comment ISNd could be considered a branch of ISNb, which is in turn a branch of ISN (Landgraf et al., 1997).
