RESUMEN
<p><b>OBJECTIVE</b>To explore the indication law of fourteen channels acupoint that is located in the same nervous segment of T1-T12 on the back and abdomen.</p><p><b>METHODS</b>By retrieving indications of fourteen channels acupoint that is located in the dominating areas of T1 - T12 in LIN Zhao-geng 's New Collection of Acupuncture-moxibustion and SHEN Xue-yong's Science of meridian-collateral and acupoint, indications of fourteen channels acupoint in the same nervous segment of skin and muscle were statistically managed, respectively.</p><p><b>RESULTS</b>There was an obvious nervous segmental law of acupoint in the skin and muscle. The acupoint indication of neighboring nervous segment was similar, which was closely related to corresponding internal organs.</p><p><b>CONCLUSION</b>The acupoint indication is decided by the space of nervous segment which dominats their related organ. From aspect of nervous structure, this article confirms that acupoint indications focus on nervous segment to carry out the regulation effect of acupoint on internal organs function, which means it has superior regulation effect on internal organs disease that is located in the same or neighboring nervous segment of acupoint.</p>
