Fig. 3 Representative sections from the tibial nerve showing axonal degeneration 2 weeks after phenol nerve block by perineural injection. Note the extent and location of axonal degeneration. Minimal peripheral degeneration occurred at the distal part of the nerve fascicle; a half-thickness degeneration occurred at the proximal site, which seems to be close to the injection point (×40, hematoxylin and eosin staining). The internal scale bar length is 200μm.
