How many lumbar vertebrae are there?

Explanation:
Five lumbar vertebrae make up the lumbar region in a typical adult. The vertebral column is arranged as seven cervical, twelve thoracic, five lumbar segments, then the sacrum (usually five fused bones) and the coccyx. The lumbar vertebrae are the largest and sit between the lower thoracic vertebrae and the sacrum, bearing most of the body's weight. So the standard count is five, from L1 to L5. While some people have anatomical variations (like a lumbarized sacral segment or a sacralized L5), those are exceptions. The other options don’t match the usual anatomy.
