  20. How many bones are in the sacrum region of the spinal column? Where are they located?
    • 5
    • Fused into one structure. Attaches
    • axial skeleton to pelvic girdle
    • & lower appendicular skeleton
  21. How many bones are in the coccyx region of the spinal column?
    • 3-5
    • Partially fused
  22. What is the dens process?
    • A process found on the axis (C2)
    • On its anterior surface is an oval or nearly
