How many lumbar vertebrae are there?

Explanation:
The lumbar region has five vertebrae, labeled L1 through L5. These are the large, weight-bearing bones of the lower back, positioned between the thoracic spine above and the sacrum below. In typical adult anatomy, there are seven cervical, twelve thoracic, and five lumbar vertebrae, with the sacrum and coccyx fused. So five is the standard count for the lumbar section. Four or six would deviate from this usual arrangement, and seven corresponds to the cervical region.
