Objective 3: Describe the structure of compact bone. Cells and matrix are arranged in an orderly pattern in compact bone (Figure 6-3). Compact bone forms layers of matrix (lamellae) that are laid down around a central blood vessel. The tube that surrounds the blood vessel is the central canal, and the circular layers of matrix are called concentric lamellae. Each central canal and the concentric lamellae together (usually about five layers) make up a structure called an osteon, which may also be referred to as the Haversian system. Spongy bone Compact bone Central canal containing vessels and nerves Osteon Periosteum Osteocyte in lacuna Central canal Perforating canal Lamella (matrix) Nerve Blood vessel Figure 6-3: Compact bone. When you look at a cross-section of compact bone, you will see many osteons packed closely together. Although each osteon appears to have a circular shape, be aware that in three dimensions, each osteon has the shape of a cylinder. Notice that when circles (or cylinders) are aligned in a row, they form concentric rings.

Compact bone consists of structures called These structures consist of concentric rings of chambers called are located within the lacunae. Cytoplasmic projections or canals called connect lacunae to each other and to a that houses blood vessels and nerves.
