Questions and Answers

What is the function of interstitial lamellae in bone tissue?

  • They are responsible for bone formation directly from connective tissue.
  • They represent remnants of old Haversian systems partially obliterated by newly formed osteons. (correct)
  • They are formed on the inner surface of the bone by osteoblasts derived from the endosteum.
  • They are laid down by osteoblasts from the periosteum on the outer side of the bone.

    • Which type of ossification involves the formation of bone directly from connective tissue?

  • Intramembranous ossification (correct)
  • Periosteal ossification
  • Endochondral ossification
  • Interstitial ossification

    • What is the primary role of osteoclasts in bone remodeling?

  • Initiate intramembranous ossification
  • Form circumferential lamellae
  • Remove old bone (correct)
  • Lay down new bone matrix
