Which movement is limited by the supraspinous ligament?

• A. Extension
• B. Rotation
• C. Flexion
• D. Lateral Flexion

Answer: (C)

The supraspinous ligament runs along the tips of the spinous processes and tightens as the spine flexes forward. This makes flexion the movement most restricted by it, serving to prevent excessive forward bending. Extending the spine is limited mainly by the anterior longitudinal ligament, while rotation and lateral flexion involve other structures such as facet joints and different ligaments.
