wings are dorsally positioned. legs are ventrally positioned.
the descending neurons associated with wings are found in a thin dorsal layer.
the descending neurons associated with legs are in a larger ventral region.
However, despite the much different anatomical space discrepancy, the number of descending neurons is roughly equal.
