Light micrograph of normal human compact bone
Light micrograph of a cross-section of normal human compact bone tissue, as found in the shafts of the long bones such as the femur

Compact bone. Coloured scanning electron micrograph (SEM) of Haversian canals in compact bone. Bundles of Haversian canals form the core of compact bone

Deer antler, SEM
Deer antler. Coloured scanning electron micrograph (SEM) of a transverse section through cortical (compact) bone from the antler of a deer

Compact bone, SEM
Compact bone. Coloured scanning electron micrograph (SEM) of a freeze-fractured sample of compact bone from a knee joint. This type of bone is found in the walls of bones

LM of compact bone from a human femur

Cartilage cell, SEM
Cartilage cell. Coloured scanning electron micrograph (SEM) of a section through a chondrocyte cell (centre) in cartilage

Bone canals, light micrograph
Bone canals. Coloured light micrograph of a section through human compact bone, showing Haversian canals (circular regions). The concentric rings surrounding the Haversian canals are called lamellae

Interior of a bone, SEM
Interior of a bone. Coloured scanning electron micrograph (SEM) of a long bone fractured to show its interior. The outer layer (pink) of the bone comprises proliferating cartilage

Fossilised compact bone, SEM
Fossilised compact bone. Coloured scanning electron micrograph (SEM) of a section through fossilised compact bone. This tissue is found in the dense walls of the shafts of bones

Bone lacuna, SEM
Bone lacuna. Coloured scanning electron micrograph (SEM) of a lacuna (cavity) in a bone, filled with new bone mineral (red)

Hyaline cartilage, SEM
Hyaline cartilage. Coloured scanning electron micrograph (SEM) of a freeze-fractured section through hyaline cartilage, a semi-rigid connective tissue

Bone tissue, light micrograph

Osteoclast bone cells, artwork
Osteoclast bone cells. Computer artwork of normal osteoclasts (green) in the lacunae (spaces) of bone tissue. Osteoclasts remodel bone by degrading

Water parsnip rhizome, light micrograph
Water parsnip rhizome. Light micrograph of a cross-section through an underwater rhizome of the lesser water parsnip (Berula erecta)

Bone structure, artwork
Bone structure, computer artwork. In the interior of the bone is cancellous, or spongy, bone (left), which is found at the ends of long bones and vertebra (spine bones)

Water lily leaf stalk, light micrograph
Water lily leaf stalk. Light micrograph of a transverse section through the leaf stalk (petiole) of a water lily (Nymphaea sp.). All aquatic plants (hydrophytes) have a similar structure

Pondweed stem, light micrograph
Pondweed stem. Light micrograph of a transverse section through the stem of a pondweed (Potamogeton sp.) plant. All aquatic plants (hydrophytes) have a similar stem structure

Compact bone, light micrograph
Compact bone. Polarised light micrograph of a transverse section through compact bone tissue, showing Haversian canals (circular regions)

Osteoclasts in bone lacunae, SEM
Osteoclasts in bone lacunae, coloured scanning electron micrograph (SEM). These osteoclasts are seen in Howslips lacunae, spaces in the bone where they are responsible for remodeling the bone
