通过弹性蛋白免疫染色和常规组织学染色发现牛尾椎间盘中存在弹性纤维。这些纤维分布在磁盘的所有区域，但它们的组织因区域而异。在细胞核中心，长弹性纤维呈放射状排列。在核和环之间的过渡区域，弹性纤维的方向改变，产生纵横交错的图案。在环本身，弹性纤维似乎密集地分布在片层之间的区域，也在片层之间的“桥”中，特别是在成虫身上。弹性纤维在片层内是明显的，平行于每个片层的胶原纤维，特别是在年轻（12天）的椎间盘。在椎间盘和软骨终板之间的区域，弹性纤维似乎锚定在钢板中并终止于此。本研究的结果表明，弹性纤维有助于椎间盘的机械功能。椎间盘不同区域弹性纤维的不同组织可能与不同的区域加载模式有关。
Elastic fibres have been revealed by both elastin immunostaining and conventional histological orcein-staining in the intervertebral discs of the bovine tail. These fibres are distributed in all regions of the disc but their organization varies from region to region. In the centre of the nucleus, long (> 150 mum) elastic fibres are orientated radially. In the transitional region between nucleus and annulus, the orientation of the elastic fibres changes, producing a criss-cross pattern. in the annulus itself, elastic fibres appear densely distributed in the region between the lamellae and also in 'bridges' across the lamellae, particularly in the adult. Elastic fibres are apparent within the lamellae, orientated parallel to the Collagen fibres of each lamella, particularly in the young (12-day-old) discs. In the region between the disc and the cartilaginous endplate, elastic fibres appear to anchor into the plate and terminate there. The results of this study suggest that elastic fibres contribute to the mechanical functioning of the intervertebral disc. The varying organization of the elastic fibres in the different regions of the disc is likely to relate to the different regional loading patterns.
