The patterns of lamellae reflect the history of bone remodelling. Osteons (haversian system) with complete concentric lamellae are the most recently formed. Other lamellae, which terminate abruptly against a cement line, are the fragmentary remains of former osteons that have been partially removed and replaced during remodelling.

Number 1 indicates a recently formed osteon.
Number 2 indicates a somewhat older osteon, as demonstrated by the encroachment of osteon 1.
Number 3 indicates interstitial lamellae, representing the remnants of still older osteons.
