There are two main connecting structures between vertebrae: the first is the connection between ligaments, and there are relatively many ligaments in the connecting structures between vertebrae, mainly the anterior longitudinal ligament. The anterior longitudinal ligament is a long ligament that connects at the anterior edge of the vertebral body, from the cervical vertebrae all the way to the sacral vertebrae. The second ligament is the posterior longitudinal ligament, which is in the posterior part of the vertebral body in front of the spinal canal and is also connected from above to below. There are also interspinous ligaments connecting the vertebrae to each other, and the ligamentum flavum connecting them. The second bony connection is the articular processes between the vertebrae, which are arranged in a stacked tile pattern to provide some stability. There is also the spinous process, which is very closely aligned above and below the spinous process and is a relatively heavy structure that contributes to the stability of the intervertebral bones.
