## EXERCISE 5. Parts of a Long Bone Match the parts of a long bone with their description and/or function. Next, label the diagram of the long bone below. If you need to refresh your memory, refer to Figure 5.4 in your textbook. | | | | |---|---|---| | 1. Epiphysis | A. Site of bone elongation; growth plate | | | 2. Articular cartilage| B. Tough outer connective tissue covering | | | 3. Red bone marrow | C. Bone end | | | 4. Epiphyseal line | D. Fatty tissue in medullary cavity | | | 5. Spongy bone | E. Region between epiphysis and diaphysis | | | 6. Metaphysis | F. Hematopoietic tissue | | | 7. Diaphysis | G. Comprises the shaft | | | 8. Periosteum | H. Space in the middle of the shaft | | | 9. Endosteum | I. Covers and protects bone ends; hyaline | | | 10. Medullary cavity | J. Shaft of the long bone | | | 11. Yellow bone marrow | K. Comprises the bone ends | | | 12. Compact bone | L. Inner lining of the medullary cavity | | The image shows a long bone with the following parts labelled: - 1. Epiphysis - 2. Articular cartilage - 3. Red bone marrow - 4. Epiphyseal line - 5. Spongy bone - 6. Metaphysis - 7. Diaphysis - 8. Periosteum - 9. Endosteum - 10. Medullary cavity - 11. Yellow bone marrow - 12. Compact bone ## EXERCISE 7. Skeletal Landmarks Labeling Match the bone or landmark with its label on the diagram. | | | | |---|---|---| | 1. Iliac crest | A. | | | 2. Lateral malleolus | B. | | | 3. Greater trochanter | C. | | | 4. Occipital bone | D. | | | 5. Olecranon process | P. | | | 6. Calcaneus | | | | 7. Patella | E. | | | 8. Inferior angle of scapula | | Q | | 9. Mastoid process | | | | 10. Acromion process | F. | | | 11. Mandible | | T | | 12. Tibial tuberosity | S. | | | 13. Head of radius | H. | | | 14. Anterior superior iliac spine | | K | | 15. Ischial tuberosity | J. | | | 16. Glenoid fossa | | | | 17. Spinous process | | | | 18. Lateral humeral epicondyle | | | | 19. Xiphoid process | | | | 20. Crest of tibia | | L | ## EXERCISE 8. Label a Synovial Joint All synovial or diarthrotic joints share some common structural components. Label the sagittal section of the knee provided to review the structures of a synovial joint. If you need to refresh your memory, refer to Figure 5.24 in your textbook. | | | |---|---| | 1. | Anterior cruciate ligament | | 2. | Articular cartilage | | 3. | Bursa | | 4. | Fat pad | | 5. | Fibrous joint capsule | | 6. | Menisci | | 7. | Patella | | 8. | Patellar ligament | | 9. | Synovial fluid | | 10. | Synovial membrane | ## EXERCISE 8 BONE STRUCTURE AND FUNCTION 9. Observe the bones in Figure 8.6(a) and (b). Identify the child's hand and the adult's hand. 10. Observe Figure 8.7(a) and (b). Identify the normal bone and osteoporotic bone. The images show: - **Figure 8.6** X-rays of the child and adult hand. - **Figure 8.7** Normal and osteoporotic bone tissue.
