Accepted Answer

The haversian system (osteon) is a cylindrical arrangement of dense bone, consisting of concentric layers of mineralized matrix called lamellae, surrounding a central canal called the haversian canal. This system is characteristic of compact bone, as opposed to cancellous bone, which has a more open, spongy structure.
