Permanent axotomy, a model of axonal atrophy and secondary segmental demyelination and remyelination

Abstract

Abstract Permanent axotomy in cats produced by hind limb ablation results in sequential pathological alterations of myelinated fibers of the proximal nerve stump. The changes are like those previously described for human uremic neuropathy and such system atrophies as Friedreich's ataxia; axonal atrophy → myelin wrinkling → nodal lengthening and internodal demyelination → remyelination.
