|Ligament: Ligamenta flava|
|Vertebral arches of three thoracic vertebræ viewed from the front.|
|Median sagittal section of two lumbar vertebræ and their ligaments.|

They are best seen from the interior of the vertebral canal; when looked at from the outer surface they appear short, being overlapped by the laminæ.
Each ligament consists of two lateral portions which commence one on either side of the roots of the articular processes, and extend backward to the point where the laminæ meet to form the spinous process; the posterior margins of the two portions are in contact and to a certain extent united, slight intervals being left for the passage of small vessels.
Each consists of yellow elastic tissue, the fibers of which, almost perpendicular in direction, are attached to the anterior surface of the lamina above, some distance from its inferior margin, and to the posterior surface and upper margin of the lamina below.
Their marked elasticity serves to preserve the upright posture, and to assist the vertebral column in resuming it after flexion.
