  3. Topic 1– 6 Points • Q:Name 2 minerals that Bones store. • A: Calcium (Ca) and Phosphorus (P)

  4. Topic 1– 7 Points • Q:Describe any other function of bones besides storing minerals. • A: Attachment sites for muscles and ligaments. • B. Supports the body weight. • C. Protects internal organs. • D. Stores Fat. E. makes blood cells.

  5. Topic 1– 8 Points • Q:Give one example of a long bone. • A: Humerus, ulna, radius, Femur, tibia, fibula.

  6. Topic 1– 9 Points • Q:Give one example of a short bone: • A: Carpals (wrist bones), Tarpals (ankle bones).

  7. Topic 1– 10 Points • Q:Give one example of a flat bone. • A: Scapula, cranial bones.

  8. Topic 2– 6 Points • Q:Give one example of an irregular bone. • A: vertebra, mandible

  9. Topic 2– 7 Points • Q:How are sesamoid bones different from the other bone types. • A: are not attached to any other bones. Example : Patella (knee cap)

  10. Topic 2– 8 Points • Q:What is the difference between the structure of compact bone versus spongy bone. • A: Compact bone is harder. Spongy bone has arch structures (like pores) • B. Spongy bone is found at the ends of bone. Compact bone is in the shaft.

  11. Topic 2- 9 Points • Q:What is the difference between yellow marrow and red marrow. • A: Yellow marrow stores fat. Red marrow produces Blood Cells.

  12. Topic 2- 10 Points • Q: Describe the difference between the bones cells called osteoblasts vs osteoclasts. • A: Osteoblasts build bone. Osteoclasts break down bone.

  13. Topic 3- 6 Points • Q: Which part of the long bone is the diaphysis? • A: The center long shaft of long bones.

  14. Topic 3– 7 Points • Q: What part of long bones is known as the epiphysis. • A: The spongy ends of long bones.

  15. Topic 3– 8 Points • Q: What is the epiphyseal line. • A: The thin line made of cartilage at the end of long bones where growth occurs.

  16. Topic 3– 9 Points • Q: Give two examples of ball and socket joints. • A: Shoulder and hip joints.

  17. Topic 3– 10 Points • Q: Give two examples of hinge joints: • A: elbow and knee joint.

  18. Topic 4– 6 Points • Q: Give one example of an immovable joint. • A: Sutures in the skull.

  19. Topic 4– 7 Points • Q: Give an example of gliding joints. • A: carpals (wrist) and tarsals (ankle)

  20. Topic 4– 8 Points • Q: Why do babies have more bones than adults? • A: Many of their bones have not fused permanently yet.

  21. Topic 4– 9 Points • Q: Describe the difference between the body movements : Flexion vs. Extension. • A: Flexion = bending joint • B. Extension = straightening joint

  22. Topic 4– 10 Points • Q: Describe the difference between abduction vs adduction. • A: abduction= moving away from the midline of the body. • B. adduction= moving toward the midline of the body.

  23. Topic 5– 6 Points • Q: When you reach out to shake someone’s hands, are you doing pronation or suppination? • A: suppination.

  24. Topic 5– 7 Points • Q: Put the following vertebrae bones in order from your neck region down: coccyx, cervical, lumbar, thoracic, sacrum • A:cervical, thoracic, lumbar, sacrum, coccyx

  25. Topic 5– 8 Points • Q: What is the difference between true and false ribs. • A: True ribs are attached to the sternum. • B. False ribs are attached to the ribs • above them.

  26. Topic 5– 9 Points • Q: Name two bones of the pectoral girdle: • A: Scapula and clavicle

  27. Topic 5– 10 Points • Q: Name three bones of the pelvic girdle: • A: Hip bones, sacrum, coccyx.
