The anterior longitudinal ligament is composed of three layers: the superficial, intermediate, and deep layers.

The superficial layer has the longest fibers that can extend over several vertebrae, while the deep layer only extends between adjacent vertebrae. The fibers have particularly strong attachments to the annulus fibrosus of the intervertebral discs.
