Structure of a long bone

  1. The traditional model for overall bone structure.
    Long bone
  2. The central portion of the bone.
    Diaphysis
  3. The diaphysis is composed primarily of what bone tissue?
    Compact bone
  4. The hollow center of the bone from which the diaphysis surround to, is what we call the ___________.
    medullary cavity
  5. The ends of the long bone is called the _________.
    epiphysis
  6. The epiphysis is mostly composed of what type of bone tissue?
    Mostly spongy bone with an outer layer of compact bone.
  7. Within joints the end of the long bone is covered with what type of hyaline cartilage?
    Articular cartilage
  8. It is where the growth of bone length occurs. Also known as the growth plate.
    Epiphyseal
  9. Where can you find the epiphyseal?
    It is between the epiphysis and the diaphysis.
  10. Growth in length of the bones such as the leg, arm, forearm and thigh occurs at _________.



    A. Both the ends of the long bone's diaphysis
  11. Growth in length of the bones such as the hands and foot occurs at __________.



    B. One end of the diaphysis.
  12. What happens to the epiphyseal (growth plate) when the bone stops growing.
    The epiphyseal plate becomes ossified (hardened; opposed to change) and is called the epiphyseal line.
  13. Site of blood cell formation.



    C. red bone marrow
  14. It is mostly adipose tissue.



    A. yellow bone marrow
  15. In a fetus before and after birth, their bones usually contain mostly of _________.



    C. red bone marrow
  16. During development (1)________ bone marrow is usually replaced by(2) ________ bone marrow.
    • 1.Red bone marrow
    • 2.Yellow bone marrow

    Yellow marrow completely replaces the red bone marrow in the long bones of limbs,except for some red bone marrow in the proximal (near) part of the arm bone and thigh bones.
  17. What bone in the body is used as the main source of donated red bone marrow, and why?
    Hip bone: it is a large bone with more red bone marrow than smaller bones and it can be accessed relatively easily.
  18. A double layered, connective tissue membrane covering the outer surface of the bone.



    C. periosteum
  19. The outer surface of the periosteum contains:



    C. blood vessels and nerves
  20. The inner surface of the periosteum contains:



    B. bone cells:osteoblast and osteoclast

    It contains a single layer of bone cells.
  21. Tendons and ligaments attach to bones become __________ with the periosteum.



    B. continuous

    Some collagen fibers of the tendons or ligaments penetrate the periosteum (connective tissue membrane covering the outer surface of the bones), to strengthen the attachment of tendons or ligaments.
  22. A single layer, connective tissue membrane covering the inner surface of the bone.



    A. endosteum
  23. What bone cells can be found at the endosteum of the bones.
    osteoblast and osteoclast
