Differences in ligamenta flava among some mammals.
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.
