In Plain Language:
Every person has a backbone or spine made up of different bone pieces linked together called vertebrae – 7 in the neck, 12 in the mid-back, and 5 in the lower back (lumbar). At the very bottom are fused vertebrae called the sacrum and coccyx. Some people are born with too many or too few vertebrae in the lumbar region or sacrum. Vertebrae can also link together improperly. All of these issues are lumped together and called “transitional spinal anatomy.”
