1. cartilage forming cells in the srrounding perichondium secrete new matrix against the external face of the existing cartilage
    appositional growth
  2. lucunae bond chondrocytes divide and secrete new matrix expanding the cartilage from within
    interstitial growth
  3. are considered longer than they are wide. has a shaft plus two ends. includes all limb bones except patella, wrist, and ankle bones
    long bones
  4. made of some variety of cartilage tissue, which consists primarily of water.
    skeletal cartilage
  5. acts like a girdle to resist outward expansion when the cartilage is compressed. Contains teh blood vessels from which nutrients diffuse throught the matrix to reach the cartilage cells
  6. looks like frosted glass. provides support with flexiblility and resilence.
    hyaline cartilage
  7. forms the long axis of the body and includes the bones of the skull, vertabrae, and rib cage. Involved in protecting, supporting and carrying other body parts
    axial skeleton
  8. consists of the bones of the upper and lower limbs and the girdles that attach teh limbs to the axial skeleton
    appendicular skeleton
  9. roughly cubed shape. example are bones of the wrist and ankles
    short bones
  10. shaped like a sesame sead, special type of short bone that form in the tendons.
    sesamoid bones
  11. the external layer is consisted of
    compact boe
  12. the inner layer is
    spongy bone aka cancellous bone
  13. shaft, forms the long axis of the bone. constructed of thick collar of compact bone that surrounds the central medullary cavity.
  14. medullary cavity is also called the
    marrow cavity
  15. are the bones ends. Compact bone forms the exterior, and spongy bone contains the interior.
  16. tufts of collagen fibers that extend from its fibrous layers into the bone matrix
    perforating(sharpey's) fibers
  17. in flat bones, the spongy tissue is called
  18. hematopoietic tissue,found within the trabecular cavities of spongy bone of long bones and in the diploe of flat bones.
    red marrow
  19. matrix tube, little plate
  20. contains small blood vessels and nerve fibers that serve the needs of the osteons cells.
    haversians canal
  21. spider shaped mature cells
  22. hairlike canals connect lucanae to each other and central canal
  23. lie at the right angles to the long axis of the bone and connect the blood and nerve supply of to the periosteum to those in the central canals and medullary cavity
    volkmans canal
  24. lying between intact osteons are incomplete lamelle called
    intersistial lamelle
  25. located just deep of the peristeum and superfical to the endosteum. extend around the entire circumference of the diaphysis and efictively resists twisting of the long bone
    circuumference lamellae
  26. mineral salts, largely calcium phosphates present in the form of tiny crystals surroundng the collagen fibers in the extracellular matrix
  27. results in the formation of cranial bones of the skull and clavicles. all bones that are formed are flat boons
    intramembranous ossification
  28. process which begins in the second month of development, uses hyaline cartilage as models for bone construction
    endochondral ossification
  29. the formation of long bone typically begins in the center of the hyaline cartilage shaft at a region called
    primary ossification center
  30. occurs wherever bone is injured or added strength is required
    bone deposit
  31. unmineralized band of gauzy looking bone matrix
    osteoid seam
