    2. False.

  5. Which of the following is not a function of periosteum?
    1. anchor blood vessels and nerves to the surface of a bone
    2. provide a smooth surface at the articulation between bones
      3.
    3. provide a fibrous surface for the attachment of tendons and ligaments

      2.
    2. the total lack of spongy bone tissue
    3. the larger size of their medullary cavities
    4. the absence of periosteum in contact with the bone tissue
