motor nerve fiber

1. More expression of CGRP at second and fourth week was observed in laser irradiation group comparing to the control group. The positive substance was mainly found in motor neuron of the anterior horn and in sensory nerve fiber in the posterior horn.
   第2周及第4周时激光照射组CGRP的表达高于对照组，阳性表达主要集中于脊髓前角运动神经元和背根感觉纤维；
2. It was showed that under normal contraction, the motor nerve terminals of the muscle were initially excited by magnetic stimulation and the Ia fiber and/ or the receptors of the muscle were indirectly excited.
   结论：正常伴肌收缩时，磁刺激很可能先兴奋肌肉运动神经末梢致肌肉运动，间接兴奋肌肉Ia纤维或（和）肌肉深部感受器；
3. However, due to the proportion of the number of nerve fibers suitable for transposition in the motor area to that in the receiving area is only 1 to 10, it is difficult to find enough nerve fiber for the transposition.
   但可供移位的动力神经与受区神经的纤维数的比例为1：10，很难再找到可供移植的神经了。
