The anterior aspect of the vertebral bodies houses which ligament?

• A. Anterior Longitudinal Ligament (ALL)
• B. Posterior Longitudinal Ligament (PLL)
• C. Ligamentum flavum
• D. Interspinous ligament

Answer: (A)

The anterior longitudinal ligament lies on the front surface of the vertebral bodies and intervertebral discs, forming the spine’s anterior boundary. Its position explains why it’s responsible for limiting extension and providing front-to-back stability of the column. In contrast, the posterior longitudinal ligament runs along the back of the vertebral bodies inside the spinal canal, the ligamentum flavum spans between the laminae on the posterior wall of the canal, and the interspinous ligament sits between adjacent spinous processes.
