The ligamenta flava of the thoracolumbar spine of mammals with great spinal mobility have a larger content of elastin than in animals with little spinal motion. The elastin content is also higher in the ligamenta flava of mammals with arched backs and prolonged sitting posture than in nonsitting mammals with the vertebral column in the shape of a flat bow. The ligamentum flavum appears to be important; a) in the control of intervertebra movements, b) in providing intrinsic stability to the spine in the sitting and standing postures and c) in maintaining a smooth surface in the posterior wall of the spinal canal and neural foraminae.
脊柱活动度大的哺乳动物胸腰椎的黄韧带比脊柱活动度小的动物含有更多的弹性蛋白。与脊柱呈扁平弓形的非坐姿哺乳动物相比，背部弓形且长时间坐姿的哺乳动物的黄韧带中弹性蛋白含量也更高。黄韧带似乎很重要：a）在控制椎间运动方面；b）在为坐姿和站姿的脊柱提供内在稳定性方面；c）在维持椎管后壁和神经孔的光滑表面方面。
