[摘 要] 目的：探讨合谷穴与口面部联系的形态学基础。方法：采用荧光素单标记和双标记法，将荧光素碘化丙啶(PI)和双苯甲亚胺(Bb)分别注入“合谷”穴区和“四白”穴区，取同侧脊神经节颈1～颈8，胸1～胸2，颈上、中、下交感节及三叉神经半月节，荧光显微镜下观察计数。结果：在脊神经节颈5～颈8观察到大量PI单标记细胞，主要分布于颈6～颈7，在三叉神经半月节也可见大量Bb单标记细胞，另外在三叉神经半月节可见少量PI～Bb双标记细胞，占标记细胞的4.5%。结论：三叉神经半月节有向“合谷”穴和“四白”穴 的分支投射，这可能是“面口合谷收”的形态学基础。[主题词] 荧光双标术；穴，合谷；口颌系统/神经支配；神经节，脊

    ABSTRACT Objective To study on morphological link of Hegu (LI 4) with the face and mouth. Methods Fluorescein single-label and double-label methods were used, fluorescein propidium iodide (PI) and bi-benzylmethy benzhy dryl imine (Bb) were respectively injected into Hegu (LI 4) point area and Sibai (ST 2) point area. Ipsilateral spinal ganglia C1-C8 ......
