| Flat Bones | thin, flattened, and often curved bones that protect internal organs and provide broad surfaces for muscle attachment |
| Irregular Bones | bones with complex, unique shapes that do not fit into the other categories of long, short, flat, or sesamoid bones |

| Epiphysis | the rounded end or tip of a long bone. |
| Epiphyseal Line | the solid bone remnant of a childhood growth plate (epiphyseal plate) after it stops growing and turns completely into bone |
| Metaphysis | the wide, flared neck portion of a long bone located between the central shaft (diaphysis) and the rounded end (epiphysis) |
| Medullary Cavity | the hollow, central space inside the shaft of long bones |
| Yellow Bone Marrow | a soft, fatty tissue found in the central cavities of long bones that primarily stores energy and contains specialized stem cells |
| Periosteum | dense, fibrous membrane that covers the outer surface of almost all your bones |

| Osteoclast | brakes down old bone tissue |
| Canaliculi | microscopic channels or small passageways found within bodily structures like bones, the liver, and eyes |
| Lamellae | thin, flat layers, plates, or membranes found in various biological, botanical, and structural systems |
| Endosteum | a thin membrane of connective tissue that lines the inner cavities and surfaces of bones |
