Which ligament limits lateral flexion?

Which ligament limits lateral flexion?

• A. Nuchal Ligament
• B. Supraspinous Ligament
• C. Interspinous Ligament
• D. Intertransverse Ligament

Answer: (D)

Lateral flexion is the side-bending of the spine, and that motion is primarily resisted by the intertransverse ligaments. These ligaments span between adjacent transverse processes, forming a connective bridge that limits side-to-side movement and helps stabilize the vertebral segments during unilateral loads. The other ligaments are more associated with restricting flexion: interspinous and supraspinous ligaments limit forward bending of the spine, while the nuchal ligament supports the cervical region and also helps constrain flexion rather than lateral bending. So the intertransverse ligament is the best fit for limiting lateral flexion.
