Bone – In this specialized connective/supporting tissue

• The extracellular matrix is mineralized and
• Contains much collagen and proteoglycan aggregates.

Carefully examine the gross specimens of bone cut transversely and longitudinally and note regions of compact and cancellous tissue, trabeculae, medullary cavity, etc. (Fig. 8-1).

Review the meaning of the following terms and explain their interrelationships

• Woven bone
• Lamellar bone
• Compact bone
• Cancellous bone

The cells and matrix of compact bone are highly organized into units called osteons (or Haversian systems) which insure that osteocytes can receive nutrients via canaliculi.

• Despite the organization, compact bone is always being remodeled and this allows bones to gradually change their shapes.

Write down the basic aspects of bone remodelling.
