Neuron(神经元) 1. Central Chromatolysis(中央性尼氏小体溶解) Cause: axonal injury, Viral infection, deficiency of vit. B, anoxia. Morphology: NormalNeuron Central Chromatolysis Sequalae: In early stage, increased dissociated ribosome from RER may facilitate protein synthesis. The change would be reversible, if cause abolished. Insistent change may lead to neuronal death
