PN’s are arguably one of the most important structures for us to preserve as we have not mastered how to repair them to a pre-injury state with consistent positive outcomes compared to arteries. Despite cross-sectional imaging, we still segment the journey of PN’s through gross approximations of interrupted imaging slices. Conventional staining of PN’s occurs upon harvesting. Medical radiology has revealed moderate to large sized PN’s from humans with cross-sectional imaging. Anesthesiologists and pain specialists are in such demand that improving our understanding of PNs prior to anesthetic blocks or surgical intervention is critical.
