| Question | Answer |
|---|---|
| Osteo- | A prefix meaning Bone. |
| Long Bones | Bones that are longer than they are wide; they mainly support the body and help with movement. Example: femur. |
| Short Bones | Small, roughly cube-shaped bones that provide stability and support. Example: wrist bones. |
| Flat Bones | Thin, flattened bones that often protect internal organs and provide large surfaces for muscle attachment. Example: skull bones and ribs. |
| Irregular Bones | Bones with complex or unusual shapes that don't fit the other categories. Example: vertebrae. |
| Diaphysis | The shaft or long middle section of a long bone. |
| Epiphysis | The expanded ends of a long bone. |
| Metaphysis | The region between the diaphysis and epiphysis; it contains the epiphyseal plate/line. |
| Medullary Cavity | The hollow space inside the diaphysis that contains bone marrow. |
| Yellow Bone Marrow | Fat-rich marrow found mainly in the medullary cavity of adult long bones; it stores energy. |
| Periosteum | A tough layer of connective tissue covering the outer surface of bone, except where articular cartilage is present. |
| Articular Cartilage | Smooth cartilage covering the ends of bones at joints; it reduces friction and absorbs shock. |
| Spongy Bone | Lightweight, porous bone found mainly inside bones; it helps reduce weight and absorb forces. |
| Trabeculae | Thin, branching struts or plates of bone that form the structure of spongy bone. |
| Red Bone Marrow | Tissue that produces blood cells. |
| Compact Bone | Dense, hard bone that forms the strong outer layer of most bones. |
| Osteon | The basic structural unit of compact bone; also called a Haversian system. |
| Haversian Canal | A central canal running through an osteon that contains blood vessels and nerves. |
| Osteocyte | A mature bone cell that maintains bone tissue. |
| Osteoblast | A bone-forming cell that builds new bone. |
| Osteoclast | A bone-resorbing cell that breaks down old or damaged bone. |
| Canaliculi | Tiny channels connecting bone cells (osteocytes) to each other and to blood supply. |
| Lamellae | Thin layers/rings of bone tissue surrounding the Haversian canal. |
| Endosteum | A thin membrane that lines the inner surfaces of bone, including the medullary cavity. |
| Lacuna | A small space or pocket in bone where an osteocyte is located. |
| Blood Vessels | Tubes that carry blood, oxygen, nutrients, and waste through bone tissue. |
| Arterioles | Small branches of arteries that carry blood toward capillaries. |
| Venules | Small vessels that carry blood away from capillaries toward veins. |
