WHICH ONES ARE TRUE RIBS? RIBS 1-7WHICH ONES ARE FALSE RIBS? RIBS 8-12WHICH ONES ARE FLOATING RIBS? RIBS 11-12

Rib Cage

Page 27: Axial skeleton
Page 28: Axial skeleton

The Thoracic Cage

Manubrium- Is the widest & most superior portion of the sternum(the “handle” of the bony sword)

Body- Is the longest part of the sternum & forms its bulk (the “blade” of the bony sword).

Xiphoid process-represents the very tip of the “sword blade.”
