Distribution of arteries on antero-radial part of forearm interosseous membrane and their relation to acupoints

Objective: To investigate the distribution of vessels at acupoints.Methods: The distribution of arteries on the marking points at the 2nd-9th cun along the pericardium channel on forearm were observed by Chinese ink or letex perfusion.Results: The frequency of arteries distributed in the 2nd, 3rd,4th, 5th cun areas of pericardium channel were higher(≥56.3%).Conclusion: Arteries on interossous membrane of forearm along the pericardium channel has a segmental distribution.
