[Location, selection, and comparative anatomy of "Taixi" (KI3), "Shuiquan" (KI5), "Fuliu" (KI7), "Jiaoxin" (KI8), "Zhubin" (KI9), and "Yingu"(KI10) acupoints in rabbits].

OBJECTIVE: To investigate the. METHODS: for locating and selecting the acupoints of "Taixi" (KI3), "Shuiquan" (KI5), "Fuliu" (KI7), "Jiaoxin" (KI8), "Zhubin" (KI9), and "Yingu" (KI10) and the morphological structure of these acupoints in rabbits. MethodsAccording to the WHO and national standards for human acupoints and rabbit X-ray images, acupoint locations were marked using the anatomical landmarks on body surface in 10 New Zealand rabbits. The acupoints were dissected to compare the homologous and analogous tissue between rabbits and human body and thus correct the locations of these acupoints. Potentials were measured for the 10 New Zealand rabbits at the corrected locations of the acupoints and around the acupoints, and the final locations of these acupoints were determined by comparing the anatomical results and the data of potentials. Anatomical observation was performed after marking, and the relationship between acupuncture needle and adjacent structure was observed. RESULTS: above the medial malleolus on the line between "Taixi" and "Yingu"; "Yingu" was located at the medial side of the knee, at the posterior-inferior border of the semitendinosus tendon on the popliteal crease. The results of skin potentials at the acupoints suggested that "Taixi", "Shuiquan", "Fuliu", and "Zhubin" were high-reliability acupoints, "Jiaoxin" was a medium-reliability acupoint, and "Yingu" was a low-reliability acupoint. CONCLUSION: Comparative anatomy combined with imaging, surface anatomy, and electrophysiological techniques of acupoints can help with the accurate localization and selection of acupoints in experimental animals, improve the reliability of acupoint location, and enrich the comparative anatomical data of acupoints.
