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: (I) 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 fibres 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 plexuses may be of importance in elucidating the mechanisms of epidural therapies in back pain and peripheral vascular disease.
采用乙酰胆碱酯酶全层染色法，对4例16 - 22周龄的人类胎儿的脊髓硬脊膜供应神经进行了研究。脊髓腹侧硬脊膜含有密集的纵向神经丛，其神经来源有：（I）窦椎神经，（II）后纵韧带神经丛，（III）节段动脉神经根分支神经丛。背侧硬脊膜神经数量少得多，不形成明显的神经丛，也不到达背侧硬脊膜的内侧区域。背侧神经起源于硬脊膜“节间”部分水平的腹侧硬脊膜神经丛。腹侧硬脊膜神经可延伸至八个节段，相邻神经之间有大量重叠。这可能为理解节段外牵涉性硬脊膜疼痛提供解剖学基础。通路（I）和（II）的卷曲神经纤维束能充分适应脊髓硬脊膜在屈伸过程中的移位。通路（III）此前未见描述。所描述的神经丛可能对阐明背痛和外周血管疾病的硬膜外治疗机制具有重要意义。
