The spinal column in a typical adult consists of how many bones?

Explanation:
Counting bones in the adult spine hinges on how the vertebrae fuse as you mature. An adult spine has 24 movable vertebrae (7 cervical, 12 thoracic, 5 lumbar) plus the sacrum and coccyx, each a single bone formed by fusion of several vertebrae. So the total is 24 + 1 + 1 = 26 bones. At birth there are about 33 vertebrae, but fusion reduces the count to 26 in adulthood.
