Answer to the riddle: A book. Geographic answer: A mountain Range. Science answer: Sharks. (Instead of bones, sharks have a spine and cartilage)

I'm assuming you mean the spine - The highest 7 vertebrae make up the cervical spine (or C spine) = the neck The next 12 vertebrae (where your ribs attach) make up the thoracic spine (or T spine) - this can also be referred to as the dorsal spine The next 5 vertebrae down make up the lumbar spine (or L spine) = the lower back And the sacrum is the very bottom of the spine made of 5 fused vertebrae.
