To explore the relationship between the distributions of posterior ramus of spinal nerve (PRSN) and locations of acupoint in low back through anatomical observation.
The regional anatomy was performed at five corpses to observe the distribution of erector spinae muscle and PRSN in areas of points and back- points in low back.
The T, L, L, L and L PRSN distributed on both sides of the spine; the medial branches of PRSN travelled between spinalis thoracis muscle and longissimus thoracis muscle, while the lateral branches of PRSN travelled between longissimus thoracis muscle and iliocostalis lumborum muscle.
points and back- points in low back are closely associated with PRSN, particularly T, L, L, L and L.
通过解剖学观察探讨脊神经后支（PRSN）的分布与腰部穴位位置之间的关系。
对5具尸体进行局部解剖，观察竖脊肌和PRSN在腰部穴位及背部穴位区域的分布。
T₁₁、L₁、L₂、L₃和L₄脊神经后支分布于脊柱两侧；PRSN的内侧支走行于胸段棘肌与胸段最长肌之间，而PRSN的外侧支走行于胸段最长肌与腰段髂肋肌之间。
腰部穴位及背部穴位与PRSN密切相关，尤其是T₁₁、L₁、L₂、L₃和L₄。
