  25. LIGAMENTS OF THE VERTEBRAL COLUMN 1. ANTERIOR LONGITUDINAL LIGAMENT: Anterior to the vertebral bodies Is found from C2 to the Sacrum 2. POSTERIOR LONGITUDINAL LIGAMENT: Posterior to the vertebral bodies and anterior to the spinal cord Is found from C2 to the Sacrum 3. LIGAMENTUM FLAVUM: Elastic fibers make it yellow in appearance Runs from the laminae of adjacent vertebrae from C2 to the Sacrum Forms the posterior wall of the vertebral foramen along with the vertebral arches 4. INTERSPINOUS LIGAMENT: Runs from spine to spine from C2 to the Sacrum 5. SUPRASPINOUS LIGAMENT: Runs from the tip of one spinous process to the next Called the nuchal ligament in the cervical region
