Surrounding the axon is a myelin sheath, which is actually just insulation.
周围的轴突是一个髓鞘，实际上仅仅是绝缘的。

CONCLUSION: the degree of denervation is a marker for rehabilitative diagnosis of FP, and is related to the destruction degree of myelin sheath and axon.
结论：失神经支配程度是FP康复诊断的指标，并与髓鞘和轴突破坏程度有关。

Conclusion The analgesic effect of IS was presumably caused by modulation of voltage-gated sodium channels in primary sensory neurons besides structure destruction of myelin sheath and axon membrane.
