The posterior longitudinal ligament lies along which part of the vertebral column?

Anterior to the vertebral bodies External to the spinous processes Within the intervertebral discs Posterior to the vertebral bodies within the vertebral canal

Correct Answer:

Within the intervertebral discs

Explanation:

The posterior longitudinal ligament runs along the back (posterior) surface of the vertebral bodies, inside the vertebral canal, sitting between the bodies and the spinal cord. It is anterior to the spinal cord but within the canal, and it is not part of the intervertebral discs, nor is it outside the canal or on the outside of the vertebrae. This location distinguishes it from the anterior longitudinal ligament, which lies on the front surface of the vertebral bodies, outside the canal.
