本文用乙酰胆碱酯酶全染色法对4例16-22周人胎硬脊膜的神经进行了研究。腹侧硬脊膜包含一个密集的、纵向的神经丛，其接受以下神经丛的贡献：（1）窦椎神经，（II）后纵韧带神经丛，（III）节段动脉根支神经丛。硬膜背侧神经数量少，不形成明显的神经丛，也不到达硬膜背侧的内侧区域。背神经来源于硬脑膜的“鞘间”部分水平的腹侧硬脑膜丛。腹侧硬脑膜神经可延伸至8个节段，相邻神经之间有大量重叠。这可能为了解节段外牵涉性硬脑膜疼痛提供解剖学基础。路径（I）和（II）的卷曲神经纤维束提供了对屈曲和伸展期间硬脊膜移位的充分适应。途径（III）以前没有描述过。所描述的神经时相可能对阐明硬膜外治疗背痛和外周血管疾病的机制具有重要意义。
The nerves supplying the spinal dura mater were studied in four human foetuses (16-22 weeks) with the acetylcholinesterase in toto staining method. The ventral spinal dura contains a dense, longitudinally oriented, nerve plexus, which receives its contributions from: (1) the sinuvertebral nerves, (II) the nerve plexus of the posterior longitudinal ligament, (III) the nerve plexus of radicular branches of segmental arteries. Dorsal dural nerves are much smaller in number, do not form an evident plexus and do not reach the medial region of the dorsal dura. The dorsal nerves are derived from the ventral dural plexus at the level of the "intersleeval" parts of the dura mater. The ventral dural nerves may extend up to eight segments, with a great amount of overlap between adjacent nerves. This may provide an anatomical substrate for the understanding of extrasegmentally referred dural pain. The curled bundles of nerve fibers of pathways (I) and (II) provide an adequate adaptation to displacements of the spinal dura mater during flexion and extension. Pathway (III) has not been described before. The described nerve phases may be of importance in elucidating the mechanism of epidural therapies in back pain and peripheral vascular disease.
