  1. Skeletal System

  2. Fill in the skeletal body on the back page of your packet. Use pages 134 in your text book.

  3. Terminology 126 • 1. aur- 7. arthr(o)- • 2. –poiesis 8. carp- • 3. brachi- 9. cervic • 4. oss- 10. dia- • 5. burso 11. cox(a), pelv • 6. –genesis 12. dactyl, digit • 13. ax- 14. fov- • 15. front- 16. scolio • 17. corac- 18. condyl-

  4. Introduction • How many bones do you think are in the human body? • 206 • Largest Bone? • Femur • Smallest Bone? • Ossicles (ear bones)

  5. 1.Support Body Functions (5)

  6. 2. Protect organs

  7. 3. Attachment of muscles

  8. 4. Hemopoieses • The bones make blood cells from embryonic month 5 on…

  9. 5. Mineral Storage Ca2(PO4)3

  10. Anatomy • There are basically four types of bones.

  11. 1. Long Bones e.g. Femur Radius ulna humerus

  12. 2. Short bones carpals

  13. 3. Flat Bones

  14. 4. Irregular Bones

  15. Parts of a long bone • Please color code the femur. Color code letters a-g.

  16. A. Ends of the bone (Proximal and distal) Epiphysis

  17. A1: Cartilage growth plates on bone ends. (Growth plate) Epiphyseal plate

  18. (hyaline) cartilage on end of bone b bone trabeculae of spongy bone c red marrow cavity d epiphyseal plate (hyaline cartilage)

  19. a Epiphyseal plate made of hyaline cartilage is responsible for long bone growth. Note: The direction of growth is toward the diaphysis (shaft of long bone). Also Note: The newly forming spongy bone (below the growth plate) is not clearly organized as the older spongy bone in the epiphysis above the growth plate.

  20. B. Shaft of the bone, middle part. Diaphysis

  21. C.Cartilage layer to reduce pain and friction. Articular Cartilage

  22. D. Living layer surrounding bone. Nourishing and growth in width. Periosteum

  23. Looks like a sponge. Mostly in the epiphysis Contains red marrow (Makes RBC’s) Spongy bone

  24. Close together in diaphysis. Organized into concentric layers. Compact Bone

  25. Hole in the middle of the bone. Filled with yellow marrow (fat for energy storage) Medullary Cavity

  26. Surface features: (3) • 1. Projections • 2. Depressions • 3. Openings

  27. Projections • For attachments

  28. Depressions • For joints to fit together.

  29. Openings • For blood vessels and nerves.

  30. Osseous Tissue

  31. Matrix

  32. Osteocyte • Mature bone cells. • Maintain bones and assist and repair.
