Posterior longitudinal ligament

Definition

The posterior longitudinal ligament is a strong fibrous tissue band that runs along the back of the vertebral bodies from the base of the skull to the sacrum, providing support and stability to the spinal column. It helps prevent hyperflexion of the spine, protecting it from injury.
