目的:通过对大鼠膀胱经覆盖的背阔肌、背最长肌及臀中肌的神经支配的研究,了解经脉线及非经脉线神经支配的区别和经络的神经解剖学特征,从而为经络实质的研究提供形态学基础。方法:用霍乱毒素B亚单位结合辣根过氧化物酶(CB-HRP)对膀胱经经脉线及非经脉线上背阔肌、背最长肌及臀 OBJECTIVE: To understand the difference between innervation of meridian and non-meridian nerves and the neuroanatomical characteristics of meridian by studying the innervation of the latissimus dorsi, dorsalis longus and gluteus medius in the bladder of rats. Substantial research provides the morphological basis. Methods: The cholera toxin B subunit combined with horseradish peroxidase (CB-HRP) on the bladder meridian and non-menopause on the latissimus dorsi, the longest muscle and hip
