Which statement about the ALL is true?

• A. It attaches primarily to the anterior vertebral body
• B. It attaches to the intervertebral discs
• C. It is located behind the vertebral bodies
• D. It passes through the transverse foramina

Answer: (A)

The key idea is where the anterior longitudinal ligament sits and what it attaches to. This ligament runs along the front of the entire vertebral column, anchoring to the anterior surfaces of the vertebral bodies and to the adjacent anterior aspect of the intervertebral discs. Its main role is to stiffen the spine and resist hyperextension, which aligns with its position on the front of the column.

Saying it attaches primarily to the anterior surfaces of the vertebral bodies captures its main attachment pattern—these vertebral bodies are the main anchors along the length of the spine. It does connect with the intervertebral discs as well, but the strongest and most consistent attachments are to the vertebral bodies themselves, not to a position behind the spine. The ligament is located anterior to the vertebral bodies, not behind them, and it does not pass through the transverse foramina (those passages are for structures like the vertebral arteries in the cervical region). That combination of location and attachments is why this statement is true.
