The present study was designed to determine the motor nerve pathway of the facial nerve to the levator veli palatini muscle. The experiments were carried out on 10 anesthetized rhesus monkeys. Recorded and analyzed were evoked EMG responses of the levator veli palatini and the orbicularis oris muscles by electrical stimulation to both the facial nerve and its branch within the cranium. Muscle action potentials (M-waves) from the two muscles could be recognized on stimulating the facial nerve at the petrosal area of the temporal bone. On stimulating the greater petrosal nerve, M-waves from the levator muscle could be elicited. By cutting off the greater petrosal nerve at the middle cranial fossa, M-waves from the levator muscle completely disappeared on stimulating the facial nerve at the petrosal area. Results indicated that the course of the facial nerve for the levator veli palatini muscle is through the greater petrosal nerve.
本研究旨在确定面神经至腭帆提肌的运动神经通路。实验在10只麻醉的恒河猴身上进行。通过电刺激面神经及其颅内分支，记录并分析腭帆提肌和口轮匝肌的诱发肌电图反应。在颞骨岩部区域刺激面神经时，可识别出两块肌肉的肌肉动作电位（M波）。刺激岩大神经时，可引出腭帆提肌的M波。通过在中颅窝切断岩大神经，在岩部区域刺激面神经时，腭帆提肌的M波完全消失。结果表明，面神经至腭帆提肌的走行是通过岩大神经。
