Which portions of the spine have five vertebrae?

Explanation:
The spine is divided into regions with distinct counts of vertebrae: cervical has seven, thoracic twelve, lumbar five, and the sacral region is made up of five vertebrae that fuse to form the sacrum. So the only pairing where both regions have five vertebrae is the lumbar region and the sacral region. The lumbar region has five separate vertebrae, and the sacral region consists of five vertebrae that fuse into one bone.
