| Ossification | process of bone formation |
| Periosteum | fibrous connective tissue membrane that surrounds and protect the shaft of long bones |
| Remodeling | adult bones can change in density, strength and sometimes shape. |
| Axial Skeleton | Central, stable portion of the skeletal system, consisting of the skull, spinal column and thoracic cage |
| fontanel | openings in the infant skull through which the baby's pulse can be felt |
| appendicular skeleton | bones of the bodys appendages, arms and legs |

| dislocation | injury that involves displacement of a bone from its joint socket |
| Ligament | collagen and elastic fibers that connect bones to other bone |
| osteoarthritis | degenerative disease of articular cartilage, characterized by pain, swelling, range-of-motion restriction, and stiffness |
| osteopenia | reduced bone mass without the presence of a fracture |
| osteoporosis | bone mineralization and strength are so abnormally low that regular, daily activities can result in painful fracture |
| Sprain | abnormal motion of the articulating bones that result in overstretching or tearing of ligaments, tendons, or other connective tissues crossing a join |
| Stress fracture | tiny, painful crack in bone that results from overuse |
| Sutures | irregularly grooved, articulating bone sheets join closely and are tightly connected by fibrous tissue |
| symphysis | type of amphiarthrosis joint in which a thin plate of hyaline cartilage separates a disc of fibrocartilage from the bone |
| synarthrosis | fibrous joint that can absorb shock, but permits little or no movement |
| synchondrosis | amphiarthrosis joint in which the articulating bones are held together by a thin layer of hyaline cartilage |
| syndesmosis | dense, fibrous tissue binds the bones together, permitting extremely limited movement |
| tendon | tissue band composed of collagen and elastic fi bers that connects a muscle to a bone |
