In order to investigate the dorsoventral relationship between the sacral plexus and the pudendal nerve in man, morphological examination was performed on one pelvic half of a male cadaver. The second and third spinal nerves were removed en bloc and sectioned serially for three-dimensional reconstruction imaging of the selected sections. Comparison of the sequential images revealed that the root of the pudendal nerve is first situated ventral to the caudal root of the sacral plexus, and that the former and the latter are shifted cranialward and caudalward, respectively, at the point of exit from the second anterior sacral foramen.
为了研究人类骶丛与阴部神经之间的背腹关系，对一具男性尸体的一侧骨盆进行了形态学检查。将第二和第三脊神经整块切除，并进行连续切片，以便对所选切片进行三维重建成像。对连续图像的比较显示，阴部神经的根部最初位于骶丛尾根的腹侧，并且在从第二骶前孔穿出时，前者和后者分别向头侧和尾侧移位。
