  2. Compact bone Human bone – ground – cross section -- India ink – 4x objective This is a section of dried and long dead ground compact bone. The living cells are gone, leaving behind spaces that can be back-filled with India ink. The arrowheads indicate osteons or Haversian systems. An osteon is that bony tissue surrounding and a part of a single Haversian canal.

  3. Compact bone Human bone – ground – cross section -- India ink – 10x objective osteon interstitial lamellae Interstitial lamellae are layers of old bone tissue from an osteon that is bring destroyed by remodeling.

  4. Compact bone Human bone – ground – cross section -- India ink – 20x objective lamellae osteocytic lacuna Haversian canal interstitial lamellae interstitial lamellae Each osteon runs more-or-less parallel to the long axis of the bone. If you see a canal that is perpendicular, it is a Volkmann’s canal.

  5. Compact bone Human bone – ground – cross section -- India ink – 40x objective lamellae canaliculi Haversian canal osteocytic lacuna Canaliculi are tiny canals passing through the bone matrix that connect one osteocyte to another, ultimately connecting them all to the Haversian canal.
