神经调节的基本方式是反射，反射活动的结构基础是反射弧。只有反射弧保持完整，反射才能实现。反射的现象学生易于看到，但学生对反射弧的五部分结构及传导途径，感到非常抽象。本人在带领学生教育实习时，设计了用脊蛙反射分析反射弧的结构，收到了良好效果。1　材料准备可提 The basic mode of neuromodulation is reflection, and the structural basis of reflex activity is the reflex arc. Reflection can only be achieved if the reflex arc remains intact. The phenomenon of reflection is easy for students to see, but students are very abstract about the five-part structure of the reflex arc and the way of conduction. When I was leading students in educational practice, I designed a structure that uses a frog’s reflection to analyze the reflex arc and received good results. 1 Material preparation can be mentioned
