6. A depression or cavity in or on a bone; This is present in the mandible to assist with articulation
9. Tough connective tissue that attaches bones to bones
10. Type of ossification where dense connective tissue is replaced by calcium to form bones

5. Bone cell responsible for the reabsorption of bone.
7. The upper seven (true) ribs are articulate with this bone; breastbone
8. Ankle bones
11. Type of ossification in which the bone cell develops inside the cartilage
