This low magnification image is from a cross section through the wall of the shaft of a long bone. Prior to embedding and sectioning the bone was decalcified. In such preparations the cells are preserved but some of the details of the matrix structure, such as canaliculi, are lost.
The outer wall of the shaft is composed of outer circumferential lamellae, which completely circle the bone. The inner wall is composed of inner circumferential lamellae, which encircle the marrow cavity. The central portion is composed of osteons. The small "dots" seen in the bone wall are cross sections of Haversian canals whereas the short line-like structures are tangential sections of Volkmann's canals. The center of the bone shaft if filled with bone marrow.
