| fracture at epiphyseal plate | epiphyseal fracture |
| hyaline cartilage | endochondrial |
| rounded articular projection | condyle |
| blood clot forms | hematoma |
| 2 words for bone development | ossification, osteogenesis |
| bone fragments into many pieces | comminuted |
| thin plates | trabeculae |
| thin and flat ex. sternum | flat bone |
| very little blood formation in | long bones |
| connect lacunae to each other | canaliculi |
| covers bone (external) supplies bone with blood vessels, nerves | periosteum |
| fracture at skull | depression |
| control of remodeling | mechanical, hormonal |
| stimulated by growth hormone | longitudinal growth |
| increase in bone diameter | appositional growth |
| what is the diaphysis composed of? | compact bone |
| what is articular cartilage composed of? | hyaline cartilage |
| spaces for bone cells | lacunae |
| breaks incompletely | greenstick fracture |
| groove | furrow |
| 2 types of tissue | cartilage, bone |
| functions of bones | storage, protection, movement, support |
| longer than wide ex. femur | long bone |
| complex ex. vertebrae | irregular |
| expanded ends of a long bone | epiphysis |
| unit of bone structure | osteon |
| site of most blood cell production | flat and irregular bones |
| small rounded projections | tubercle |
| large rounded projection | tuberosity |
| raised area on or above condyle | epicondyle |
| bony expansion on narrowed neck | head |

| weakening of bones increased removal of calcium | osteoporosis |
| crushed | compression |
| cavity in bone filled with air line with mucous membrane | sinus |
| bone resorption | osteoclast |
