  1. SKELETON
    is a framework of bones and cartilage that performs support, movement, protection, storage of minerals, storage of fat, and blood cell production.
  2. SUPPORT
    it provides a rigid framework that supports soft tissues. The leg bones and backbone hold out bodies upright, and the pelvic girdle support the abdominal organs.
  3. MOVEMENT
    it provides places of attachment for muscles. Contraction of muscles allows bones to move at joints.
  4. PROTECTION
    it shields our internal organs, such as the heart and lungs, w/c are enclosed w/in the chest cavity, and the brain, w/c lies w/in skull.
  5. STORAGE of MINERALS
    it stores minerals, particularly calcium and phosphorous, that can be released to the rest of the body when needed.
  6. STORAGE of FAT
    it stores energy-rich fat in yellow bone marrow (the soft tissue w/in some bones). The fat can be metabolized when the energy is needed.
  7. BLOOD CELL PRODUCTION
    it produces blood cells in the red marrow of certain bones.
  8. COMPACT BONE
    very dense, w/ few internal spaces; covered by a glovelike membrane (periosteum), for nourishment of the bone.
  9. PERIOSTEUM
    contains blood vessels and nerves as well as cells that function in bone growt and repair.
  10. SPONGY BONE
    is a latticework of tiny beams and thin plates of bone w/ open areas between; mostly found in small, flat bones, such as most of the bones of the skull, and in the heads and near the ends of the shaft of long bones. also at the ribs, pelvis, backbone, sternum, filled w/ red marrow, where blood cells form.
  11. RED MARROW
    is where blood cells formed.
  12. YELLOW MARROW
    a fatty tissue used for energy storage.
  13. CARTILAGE MODEL
    a strong yet flexible connective tissue; able to divide and multiply quickly; can grow as rapidly as the fetus does.
  14. OSTEOBLASTS
    a bone-forming cells.
  15. EPIPHYSEAL
    is a plate of cartilage; commonly called the growth plate
  16. FIBROBLAST
    grown inward from the periosteum and invade the clot; secret collagen fibers that form mass called callus;
  17. OSTEOBLAST
    converts cartilaginous callus to a bony callus
  18. CALCITONIN
    removes calcium from the blood and causes it to be stored in bone.
  19. PARATHYROID HORMONE (PTH)
    causes calcium to be released from bone and reabsorbed into the blood.
  20. OSTEOPOROSIS
    a condition in w/ch there is a progressive loss in bone density.
  21. 2 Parts of Human Skeleton
    • Axial
    • Appendicular
  22. AXIAL SKELETON
    protects and supports our internal organs; Skull, Backbone, Sternum and Ribcage.
  23. APPENDICULAR SKELETON
    Pectoral girdle, Pelvic girdle, and Limbs.
