The present study examined the histochemical characteristics of the orbicularis oculi muscle (OOM) in the rat, in order to better understand the target muscle of the blink reflex-specifically, the motor endplate distribution and number in the normal, denervated, and reinnervated OOM. Assessment of the number of endplates needed to accomplish eye closure would provide critical information in the microsurgical restoration of the blink reflex in facial paralysis. Results demonstrated a 50% increase in the number of endplates of reinnervated rats, compared to denervated animals.
本研究检测了大鼠眼轮匝肌（OOM）的组织化学特征，以便更好地了解眨眼反射的靶肌肉——具体而言，是正常、去神经支配和重新神经支配的眼轮匝肌中的运动终板分布和数量。评估完成闭眼所需的终板数量将为面神经麻痹眨眼反射的显微外科修复提供关键信息。结果表明，与去神经支配的动物相比，重新神经支配的大鼠终板数量增加了50%。
