Instead, it depends largely on materials synthesized in the nerve cell body and delivered by axonal transport. Wallerian degeneration is not, however, merely deprivation of axonally transported ...

The nerve distal to the injury degenerates in a process known as Wallerian degeneration ... Regrowth of axon segments occurs only in myelinated PNS fibers, progressing at a rate of 1 to 4 ...

When combined with spectroscopy, MRI allows axonal damage to be quantified ... the ubiquitin proteasome pathway is involved in Wallerian degeneration suggests that an autodestruction pathway ...
