Osteoporotic Bone
Low power scanning electron microscope image, showing
osteoporotic architecture in the fourth lumbar vertebra
of an 89 year old woman (x20). The
bone is heavily eroded in places by the action of
osteoclasts and consists mainly of thin, fragile
struts. By kind permission of Alan Boyde
Normal Bone
Low power scanning electron microscope images,
showing normal bone architecture in the third lumbar
vertebra of a 30 year old woman (x20).
Strong, interconnected plates of bone are visible.

Normal Bone
Very low power scanning electron microscope image, showing
normal bone architecture in the fourth lumbar vertebra of
an 41 year year old man (x8). A regular pattern
of interconnected plates and thick struts of bone can be seen. By kind permission of Alan Boyde

Osteoporotic bone architecture
Low-power scanning electron micrograph of osteoporotic
bone architecture in the 3rd lumbar vertebra of
a 71 yr old woman. Marrow and other cells have been
removed removed to reveal eroded bone elements.

Comparison of normal and osteoporotic bone architecture
Time lapse movie of rat osteoblasts. This dense
field shows several hundred cells, including a few undergoing
mitosis. Note that many osteoblasts display large, waving
processes, resembling cilia. The sequence is speeded
up 200 times.
