足三里穴是中医学中最有效的穴位之一。针刺[猫或兔]足三里穴对刺激腓神经引起的下颌运动反应（JMR）和二腹肌肌电图（dEMG）有明显的抑制作用。通过切断腓神经并阻断A-β-受体，这种作用被减弱或消除。和一些A-δ神经纤维当电刺激足三里穴时，A-β-内啡肽的比例大于正常比例。纤维被激活。此时的局部传入纤维组成包含更多的有髓鞘纤维、更多的大尺寸纤维和更多的A-β-纤维比非穴位。足三里穴的组成和活动中大传入纤维的这种优势被认为是该穴在其结构和功能方面的基本特征之一，并有助于其强大的针灸效果。
Acupoint zusanli is one of the most effective points in traditional Chinese medicine. Needling [cat or rabbit] point zusanli has a significant suppressive effect on jaw movement response (JMR) and electromyogram of digastric muscle (dEMG) induced by peroneal nerve stimulation. This effect is weakened or abolished by sectioning the peroneal nerve and blocking A-.beta.- and some A-.delta.-fibers in the nerve. When the point zusanli is stimulated electrically, a larger-than-normal proportion of A-.beta.-fibers is activated. Local afferent fiber composition at this point contains more myelinated fibers, more large-sized fibers and more A-.beta.-fibers than non-acupoints. This predominance of large afferent fibers in the composition and activity of point zusanli is thought to be one of the fundamental characteristics of the point in regard to its structure and function and contributes to its powerful acupuncture effect.
