Explain how the anatomy of compact bone differs from that of spongy bone
What will be an ideal response?
Compact bone is composed of osteons (Haversian systems). Concentric rings of matrix, called lamellae, are situated around a central (Haversian) canal. The rings and central canal constitute an osteon, or Haversian system. Other canals, called canaliculi, spread outward from central canals to connect to lacunae which house osteocytes.
Spongy bone is open, airy, and spiky. It is composed of small, needlelike pieces of bone. Spongy bone lacks osteons and the network of canals visible in compact bone.
