• Haversian canals
  • Run longitudinally through the bone
  • Carry anastamosing and branching blood vessels, connecting with bone marrow cavity and periosteum
  • Surrounded by concentric bony lamellae
    • Rows of interconnected lacunae within, contain osteocytes (communicate by channels in young bones)
• Haversion canals + lamellae + osteocytes = Haversion system
