have up to 6-7 plates, indicating greater bone strength.
PFCs are fluorescent calcium chelating agents taken up by live maturing osteoid and remain until the osteon
The secondary osteons
of the deepest region of the cortex have wide open vascular spaces suggesting that they are not fully developed.
Active cortical remodeling was present, with the osteons
filled with new bone centrally as evidenced by the darker histologic staining.
have been found to have tetracycline markers bound into the cement of their osteons
, thereby making it theoretically possible to use modern tetracycline-based methods on ancient remains to determine Haversian system production rates for the Nubian individuals.
The plates between osteons
are from the same material and are coincident with them .
clavipes have a more extensive trabecular region with osteons
and irregular resortion arcas.
Hard bone is composed of units called osteons
, which are composed of tightly packed, concentric layers known as lamellae.
Histologically, the experimental femurs demonstrated natural remodeling processes with new osteons
As part of the interactive summary, students read a text selection about bones and identified the vocabulary words they did not know, including osteons
, cancellous, and marrow.
In addition there are more active osteons
per gram in trabecular bone to accomplish resorption and deposition.
Cross-sectional and longitudinal microscopic views reveal tightly packed and aligned lamellar osteons
