Bone (Cross section) : Observe Haversian canals surrounded by 6-22 concentric lamellae, lacunae with canaliculi and osteocytes (osteon or Haversian system), interstitial lamellae between Haversian lamellae (View image)
Bone (Longitudinal section) : Observe longitudinally oriented Haversian canals communicating with each other through transverse channels, lacunae with canaliculi and osteocytes
Spongy bone : Observe irregular trabaculae of bone with lacunae occupied by osteocytes. Haversian canals are absent. Bone marrow cells are observed in spaces between trabaculae (View image)
