Posterior longitudinal ligament

The posterior longitudinal ligament ( " posterior longitudinal ligament " ), in animals as posterior longitudinal ligament ( " back -side longitudinal ligament " ), is a longitudinal band of the spine. It consists of collagenous connective tissue taut and connects the individual vertebrae at the back of each other and thus lies within the vertebral canal. It is associated with the vertebral bodies only loosely, but firmly with the discs. It starts on the second cervical vertebra and extends to the sacrum.

The posterior longitudinal ligament is one next to the anterior longitudinal ligament, ligamentum supraspinal and nuchal ligament to the long spine bands. According to another classification, it belongs to the anterior longitudinal ligament of the vertebral ligaments, which are the other, called the vertebral arch bands juxtaposed.
