Question at position 11 Osteon is reffered to be: Forming unit of spongy bone Forming unit of compact bone Forming unit of cartilage Forming unit of nervous system

Question

BlackTom AI · Accepted Answer

The question asks about the osteon and its classification as a forming unit in bone tissue.
Option 1: 'Forming unit of spongy bone' — This is not correct. Spongy (trabecular) bone is composed of a lattice of trabeculae and does not have osteons as its basic structural unit. The osteon is specific to compact bone.
Option 2: 'Forming unit of compact bone' — This is correct. An osteon, or Haversian system, is the fundamental structural unit of compact bone, consisting of concentric lamellae around a central (Haversian) canal, with lacunae containing osteocytes and interconnected by canaliculi.
Option 3: 'Forming unit of cartilage' — This is incorrect. Cartilage has a different organizational unit (chondrocytes within lacunae in cartilage matrix) and does not form osteons.
Option 4: 'Forming unit of nervous system' — This is incorrect. The nervous system has its own distinct cellular and tissue organization, not related to bone osteons.
