| Location of red bone marrow | Spongy bone |
| Cartilage cells | Chondrocytes |
| Bone-forming cells | Osteoblasts |
| Shaft of a long bone | Diaphysis |
| Hollow space in the shaft | Medullary cavity |
| Expanded portion of the long bone at its ends | Epiphysis |
| Fibrous connective tissue membrane that covers the outer surface of long bone | Periosteum |

| Elevated levels of a hormone that could cause premature closure of the epiphyseal plates | Testosterone |
| A hormone that is necessary for proper bone formation | Thyroxine |
| A painful infection of the bone often caused by bacteria | Osteomyelitis |
| A condition occurs with aging that causes a gradual reduction in bone mass | Osteopenia |
| Hypersecretion of parathyroid hormone would produce changes in the bone similar to those associated with | Osteomalacia |
