Bone Terms

Osteon of compact bone

surrounds the central canal; the haversian canal

Lacunae containing osteocytes

a small space containing an osteocyte in bone or a chrondrocyte in cartilage

Lamellae

a thin, plate-like structure or membrane

Osteon

cylindrical structures that are several millimeters long; the functional unit of compact bone

Periosteum

dense layer of vascular connective tissue enveloping the bones except at the surfaces of the joint

Trabeculae of spongy bone

each of a group of partitions formed by bands or columns of connective tissue

Canaliculi

microscopic canals between the lacunae of ossified bone

Volkmann's Canal

perforating holes in atomic arrangement within cortical (compact) bone; within osteons, interconnects itself, the haversian canals, and the periosteum

Haversian canal

within the compact bone, lamellae fuse to form the concentric layers that form the channels (canals) that allow capillaries and nerve fibers to go through
