The compact bone around it and in the diaphysis is formed by a series of Haversian systems (osteons).
Under polarized light microscopy and especially axial sections, the Haversian systems of the periosteum were of different sizes, had variable degrees of maturation, and contained immature bone.
The microscopic structure of mammalian bone consists of repeating units called Haversian systems. Each system has concentric layers of mineralised matrix, which are deposited around a central canal containing blood vessels and nerves that service the bone.
