Damage to the neuromuscular junction following prolonged retraction can also lead to muscle denervation.
持续长时间牵拉造成神经肌肉接头处的损害亦导致肌肉去神经支配。
Results The myocyte diameter and cross section were reduced progressively along with the duration of muscle denervation.
结果肌细胞直径及截面积随失神经支配时间延长呈进行性下降；
Objective: To explore the morphological changes in orbicularis oculi muscle and orbicularis oris muscle after denervation.
目的：探讨不同程度失神经支配后，眼轮匝肌和口轮匝肌的形态学变化。
