This study attempted to characterize neural elements within the human cervical intervertebral disc. Cervical intervertebral discs were obtained from four adult human subjects at autopsy. Discs were stained in bulk with gold chloride, sectioned, and viewed with the light microscope. Nerve fibers appeared to enter the disc in the posterolateral direction and course both parallel and perpendicular to the bundles of the anulus fibrosus. Nerves were seen throughout the anulus but were most numerous in the middle third of the disc. Receptors resembling Pacinian corpuscles and Golgi tendon organs were seen in the posterolateral region of the upper third of the disc. These results provide further evidence that human cervical intervertebral discs are supplied with both nerve fibers and mechanoreceptors.
本研究试图对人类颈椎间盘内的神经成分进行特征描述。颈椎间盘取自四名成年人类受试者的尸体解剖。椎间盘整体用氯化金染色，切片后用光学显微镜观察。神经纤维似乎从后外侧方向进入椎间盘，并与纤维环束平行和垂直走行。在整个纤维环都能看到神经，但在椎间盘的中三分之一处数量最多。在椎间盘上三分之一的后外侧区域可见类似环层小体和高尔基腱器官的感受器。这些结果进一步证明人类颈椎间盘同时具有神经纤维和机械感受器。
