|
|
Term
|
Definition
| The shaft; a heavy wall of compact bone, or dense bone |
|
|
Term
|
Definition
| Wide part at each end of bone; mostly spongy (cancellous) bone |
|
|
Term
|
Definition
| Where diaphysis and epiphysis meet |
|
|
Term
|
Definition
| Resembles a sandwich of spongy bone; Between two layers of of compact bone |

Definition
| Form pathways for blood vessels; Exchange nutrients and waste |
|
|
Term
|
Definition
| Help synthesize bone proteins |
|
|
Term
|
Definition
| Mature bone cells that maintain the bone matrix; Do not divide |
|
|
Term
| TWO MAJOR FUNCTIONS OF OSTEOCYTES |
|
Definition
1. To maintain protein and mineral content of matrix
2. To help repair damaged bone |
|
|
Term
|
Definition
| Immature bone cells that secrete matrix compounds (osteogenesis); osteoblasts surrounded by bone become osteocytes |
|
|
Term
|
Definition
| Mesenchymal stem cells that divide to produce osteoblasts; assist in fracture repair |
|
|
Term
|
Definition
| Secrete acids and protein-digesting enzymes; dissolve bone matrix and release stored minerals (osteolysis) |
|
|
Term
|
Definition
| Bone building (by osteoblasts) and bone recycling (by osteoclasts) must balance |
|
|
Term
|
Definition
| The basic unit of compact bone |
|
|
Term
|
Definition
1. Isolates bone from surrounding tissues
2. Provides a route for circulatory and nervous supply
3. Participates in bone growth and repair |
