Which ligaments are the major ligaments in the lumbar spine?

Three of the more important ligaments in the spine are the Ligamentum Flavum, Anterior Longitudinal Ligament and the Posterior Longitudinal Ligament.

Primary Spinal Ligaments Include:

Ligament Spinal Region Limits…
Supraspinous Thoracic & Lumbar Flexion
Interspinous Lumbar Flexion
Intertransverse Lumbar Lateral flexion

Why anterior longitudinal ligament is stronger than posterior longitudinal ligament?

While anteriorly the ligament is thin due to the elastic fibers, the posterior capsule of each posterior joint is thicker due to the collagenous content.

Where is the strongest ligament in the body located and what does it connect?

The iliofemoral ligament is the strongest ligament in the body and attaches the anterior inferior iliac spine (AIIS) to the intertrochanteric crest of the femur.

What does the posterior longitudinal ligament do?

The posterior longitudinal ligament connects and stabilizes the bones of the spinal column. It runs almost the entire length of the spine, from the 2nd vertebra in the cervical spine (neck) all the way down to the sacrum (end of the spine).
