Histology Slides for Bone Tissues

  • Slides are presented in order of magnification if different views are presented.

  • As you view the following slides make sure you can accomplish these goals:

  • Can you identify the tissue observable on the slides?

  • Can you identify the specific structures or layers indicated by the numbered arrows or brackets?

  • At the end of a sequence, you will find the answers to the above for each slide.

Slides 2 3 compact bone l.jpg

Slides 2-3 Compact Bone

  • Osteon, the basic structural and functional unit of compact bone.

  • Concentric Lamellae, rings of bone matrix surrounding a Central Canal or Haversian canal

  • Lacuna, space in matrix where osteoblasts or osteocytes are found.

  • Canaliculi, passageways in the matrix for cytoplasmic extensions between osteocytes

  • Interstitial Lamellae, remnants of osteons whose matrix has been partly recycled by osteoclasts. These lamellae fill in the spaces between osteons.

  • Central Canal or Haversian Canal, passageway for blood vessels that provide nutrient to osteocytes.

  • Perforating Canal or Volkmann’s Canal, passageway for blood vessels that runs perpendicular to Central Canals. Conveys blood vessels to deeper osteons.

Slides 5 8 decalcified bone l.jpg

Slides 5-8 Decalcified Bone

  • Osteon, the basic structural and functional unit of compact bone.

  • Concentric Lamellae, rings of bone matrix surrounding a Central Canal or Haversian canal.

  • Lacuna, space in matrix where osetoblasts or osetocytes are found.

  • Canaliculi, passageways in the matrix for cytoplasmic extensions between osetocytes.

  • Interstitial Lamellae, remnants of osteons whose matrix has been partly recycled by osetoclasts. These lamellae fill in the spaces between osteons.

  • Central Canal or Haversian canal, passageway for blood vessels that provide nutrient to osteocytes.

  • Perforating Canal or Volkmann’s canal, passageways for blood vessels that run perpendicular to Central Canals. Conveys blood vessels to deeper osteons.

Slides 11 14 epiphyseal plate l.jpg

Slides 11-14 Epiphyseal plate

  • Zone of Resting cartilage, zone nearest the epiphysis at both the distal and proximal. Note the small scattered chondrocytes and lacuna.

  • Zone of Proliferating cartilage, note the stacks of chondrocytes that develop because these chondrocytes undergo mitosis to replace the chondrocytes that die at the diaphyseal side of the epiphyseal plate.

  • Zone of Hypertrophic cartilage, note increased size of the chondrocytes and lacuna in this region

  • Zone of Calcified cartilage, note that the matrix is staining darker. This is due to calcification of the matrix. Note that chondrocytes are decreased in number due to their death.
