How many lumbar vertebrae are listed?

Explanation:
Lumbar vertebrae define the lower-back portion of the spine. In the standard human spine, this region is a fixed block of bones located between the thoracic (mid-back) region above and the sacral area below, and it contains five individual vertebrae, typically labeled from top to bottom as L1 through L5. Therefore, when asked how many lumbar vertebrae are listed, the answer is the five bones that make up this region. The other numbers correspond to different parts of the spine or to the spine as a whole, not to the lumbar section.
