Anatomical Relations
The ligamenta flava are paired structures that adjoin the lamellae of adjacent vertebral foramina.

Function
The ligamenta flava keep adjacent laminae together and prevent hyperflexion. They aid in the straightening of the flexed vertebral column. The relative elasticity of the ligamenta flava prevents the ligaments from causing stenosis of the spinal canal during movement.
Structure
The fibers of the ligamenta flava are predominantly elastic. The ligaments are thickest in the lumbar region which aids postural integrity. It is composed of superficial and a deep layer, in which the fibers in each layer travel in opposing directions.
