- This nerve is considered by some authors as the most variable nerve of the lumbar plexus.

- The doubled veins may unite in front and behind the artery to form a plexus around that vessel.
- The myenteric plexus of these appendix specimens had even thicker nerve bundles connecting an increased number of ganglion cells.
