| What is the hollow cylinder found in the diaphysis; filled with yellow bone marrow | Medullary cavity |
| What are the ends of a long bone; consists of a thin layer of compact bone filled with spongy bone | Epiphysis |
| What separates the diaphysis and the epiphysis; consists of a line and the adjacent spongy bone | Epiphyseal plate |
| What is the thin membrane that lines the medullary cavity | Endosteum |
| What is the fibrous membrane that covers the surface of bone; has the potential to form bone during growth periods and fracture healing | Periosteum |
| What are the collagen fibers that attach the periosteum to the underlying bone | Perforating fibers |
| What covers the bone at joint surfaces of the epiphysis; provides slick surface that reduces friction and allows the joint to move freely | Articular cartilage |
