Topographic anatomical observations of the points of the posterior neck / 全日本鍼灸学会雑誌

ABSTRACT

The relation of needles inserted to the points of the posterior neck with the anatomical structures was investigated with dissection of four cadavers. The points investigated here are the five points of “Amon”, “Tenchuu”, “Fuuchi”, “Kankotsu”, and “Eifu”. The needles inserted to the respective points of the former three were found to penetrate the posterior atlantooccipital membrane and then the dura mater, and finally to reach the medulla oblongata. The depth from the inserted spots on the surface of the skin to the dura mater are 50, 51, and 49mm in the Amon, Tenchuu, and Fuuchi, respectively, in a cadaver with 39.1cm of circumference of the neck. Furthermore, it was found that the vertebral, the occipital, and the external carotid and the maxillar arteries were penetrated by or located near the needles which were inserted to the Fuuchi, Kankotsu, and Eifu, respectively.
