(a) Spinous process, mandibular fossa (b) Body, occipital condyles (c) Superior and inferior articular processes, jugular foramen (d) Vertebral arch, carotid canal (e) None of the above is correct 7-13
Thoracic Cage and Sternum Parts Thoracic vertebrae Ribs (12 pair) True False Sternum (manubrium, body) Fig. 7.32 7-14 Points to Remember Two major components of the human skeleton: Axial skeleton arranged along the medial axis
Appendicular skeleton connects to the axial skeleton Skull consists of: 22 bones (single and paired) 6 auditory ossicles (3 each side) and 1 hyoid Vertebral column consists of: Cervicals (7) Thoracics (12) Lumbars (5) Sacrum (5, fused)
Coccyx (3-5, fused) Rib cage has true (bone) ribs and false (cartilage) ribs 7-15 Questions? 7-16

The action of a typical rib, which. can be likened to the movement. of a bucket's handle. The thoracic cage protects organs in the chest and provides sites for muscle attachment. Thoracic cage:(continued) Costal-vertebral articulations.
