Each group of concentric circles (each “tree”) makes up the microscopic structural unit of compact bone called an osteon (this is also called a Haversian system). Each ring of the osteon is made of collagen and calcified matrix and is called a lamella (plural = lamellae).

Diagram of a typical long bone showing both compact (cortical) and cancellous (spongy) bone. Osteons on cross-section of a bone. In osteology, the osteon or haversian system (/ h ə ˈ v ɜːr. ʒ ən /; named for Clopton Havers) is the fundamental functional unit of much compact bone.

The microscopic structural unit of compact bone is called an osteon, or Haversian system. Each osteon is composed of concentric rings of calcified matrix called lamellae (singular = lamella). Running down the center of each osteon is the central canal, or Haversian canal

Each osteon is composed of concentric rings of calcified matrix called lamellae (singular = lamella). Running down the center of each osteon is the central canal, or Haversian canal, which contains blood vessels, nerves, and lymphatic vessels.

This article provides a systematic summary of recent advances in osteons, including the structure, function, turnover, and regenerative strategies. First, the hierarchical structure of osteons is illustrated and the critical functions of osteons in bone dynamics are introduced.

The diagram above shows a longitudinal view of an osteon. Some, mostly older, compact bone is remodelled to form these Haversian systems (or osteons ). The osteocytes sit in their lacunae in concentric rings around a central Haversian canal (which runs longitudinally).

The osteon is the basic unit of structure of compact bone, comprising a central (haversian) canal and its concentrically arranged lamellae, of which there may be 4 to 20, each 3 to 7 μm thick, in a single (haversian) system; such units are directed mainly in …

Osteon consists of concentric lamellae of bone matrix arranged around Haversian canals ( Figure 1 ). Further, os- teons are separated from each other by interstitial lamellae and on the inner and...
