Damage to the neuromuscular junction following prolonged retraction can also lead to muscledenervation.
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。

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。

Muscle satellite cells increased after denervation, but then they decreased and disappeared because they could not differentiate to mature muscle fibers.
