Relationship between the distribution of spinal nerve posterior ramus and locations of acupoint in low back / 中国针灸

ABSTRACT

<p><b>OBJECTIVE</b>To explore the relationship between the distributions of posterior ramus of spinal nerve (PRSN) and locations of acupoint in low back through anatomical observation.</p><p><b>METHODS</b>The regional anatomy was performed at five corpses to observe the distribution of erector spinae muscle and PRSN in areas ofpoints and back-points in low back.</p><p><b>RESULTS</b>The T, L, L, Land LPRSN 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.</p><p><b>CONCLUSIONS</b> points and back-points in low back are closely associated with PRSN, particularly T, L, L, Land L.</p>
