5 fused vertebrae

  • superior articular process: superior projection with a facet articulation site
  • anterior sacral foramen: passageway for blood vessels and nerves
  • posterior sacral foramen: passageway for blood vessels and nerves
  • sacral promontory: anterior border of S1; important landmark for obstetricians
  • sacral canal: portion of vertebral canal
  • median sacral crest: area of fused spinous processes
  • sacral hiatus: inferior opening of vertebral canal
