Among medullary arteries we have only examined those directly arising from the vertebral artery at the cervical level. This study is about thirty anatomical samples of cervical spine removed during necropsies; there are treated by injection-dissection method. The observed variations do not allow isolation of any artery for the cervical bulge, as possible most frequently at the lumbar bulge level. We observed variations as sometimes alternate pedicles right or left, as sometimes a symmetrical aspect finishing at the same medullar level. By injecting differently colored liquids, in the right and in the left, a side prevalence has sometimes been noted but real conclusions cannot be draw without isobar and simultaneous injections.
在髓动脉中，我们仅研究了那些在颈椎水平直接发自椎动脉的动脉。本研究涉及在尸检过程中取出的30个颈椎解剖样本；采用注射解剖法进行处理。观察到的变异情况不允许像在腰椎膨大部水平那样，将任何一条动脉分离出来作为颈椎膨大部的供血动脉。我们观察到的变异情况包括：有时椎弓根左右交替，有时在同一髓质水平呈现对称形态。通过向左右两侧注射不同颜色的液体，有时会发现一侧占优势，但如果没有等压和同步注射，就无法得出确切结论。
