Skeletal System Review (Ch. 6, 7 & 8)

1. Sketch a typical long bone. Label its epiphyses (proximal and distal), diaphysis, medullary cavity,

periosteum, and articular cartilage.

2. List and describe the 4 functions of bone.

3. What is articular cartilage? What type of cartilage is it and what does it do for you?

4. What is an osteon?

5. Distinguish between spongy bone and compact bone.

6. Explain how central canals and perforating canals are related.

7. Explain how the development of intramembranous bone differs from that of endochondral bone.

8. Distinguish between primary and secondary ossification centers.

9. Distinguish among osteocytes, osteoblasts, and osteoclasts.

10. What is the epiphyseal plate?

11. Describe how a bone fracture heals.

12. Provide several examples to illustrate how bones support and protect body parts.

13. Describe a lever. How are bones like levers?

14. Describe the functions of red and yellow marrow.

15. What is the major inorganic salt stored in bone?

16. Explain the mechanism that regulates the concentration of blood calcium ions. Positive or negative?

17. What is osteoporosis?

18. Distinguish between the axial and appendicular skeletons.

19. Define joint.

20. Discuss the relative value (to body homeostasis) of immovable, slightly moveable, and freely moveable

joints.

21. List the 6 types of synovial joints. Provide an example for each.

22. Osteocytes residing in lacunae of healthy compact bone are located quite a distance from the blood vessels

in the central canals, yet they are well nourished. How can this be explained?

23. As we grow, our long bones increase in diameter, but the thickness of the compact bone of the shaft

remains relatively constant. Explain the phenomenon.

24. Yolanda is asked to review a bone slide that her professor has set up under the microscope. She sees

concentric layers surrounding a central cavity. Is this bone section take from the diaphysis or epiphyseal

plate? Explain your answer.
