Which spinal region comprises five pairs designated L1-L5?

Explanation:
The lumbar region is the lower-back segment of the spine, and it contains five vertebrae labeled L1 through L5, each giving rise to a corresponding spinal nerve pair. That’s why the designation L1-L5 points to the lumbar region. The other regions have different counts: cervical, thoracic, and sacral have their own sets of vertebrae and nerve numbers, so they don’t use L1-L5.
