| description | any structural anomaly of the ligament that runs within the vertebral canal along the posterior aspect of the vertebral bodies; it is attached mainly to the intervertebral (IV) discs and less so to the posterior aspects of the vertebral bodies from C2 (axis) to the sacrum, often bridging fat and vessels between the ligament and the bony surface; it weakly resists hyperflexion of the vertebral column and helps prevent or redirect posterior herniation of the nucleus pulposus of an IV disc; the posterior longitudinal ligament is well provided with nociceptive (pain) nerve endings and is a much narrower, somewhat weaker band than the anterior longitudinal ligament |
