Vertebral column
From DrKoop's partner site on chronic pain, ChronicPainConnection.com
This is the spine and the sacrum with the cervical (neck), thoracic (mid-back), and lumbar (lower back) vertebra. Notice how the appearance of the vertebra change as you look down the spine. The change in shape and size reflect the different functions of the neck, mid-back, and lower back.
