Bone information and comparisons
| Types: | Bones are either compact or spongy. Bones are classified into long, short, flat, irregular, sesamoid and sutural bones. |
| Function: | Protect the body against mechanical damage, assist in the movement of the body, provide a framework and shape for the body, store minerals, and produce red blood & white blood cells. |
| Structure: | Bones are made up mostly of osteoblasts (progenitor cells), osteocytes (mature bone cells), and osteoclasts (large cells that breakdown bone tissue for growth and repair). A bone is highly vascularized. |
| Location: | Bones make up the majority of the axial and appendicular skeleton. |
| Fibrous Covering: | Periostium, rich in sensory nerve endings. |
