| layer of hyaline cartilage covering the epiphyses, where bones articulate |
|
|
Term
|
Definition
| thin, fibrous membrane which lines the medullary cavity and the spaces of spongy bones. |
|
|
Term
|
Definition
Specialized tissue that produces blood cells.
1. Found in the medullary cavities of most bones in children.
2. In adults, only skull, ribs, sternum, vertebrae, and end of long bones produces red blood cells. |
|
|
Term
|
Definition
| formation of red blood cells in the bone marrow. |

Term
|
Definition
bone cells
located in tiny chambers call lacunae.
Have extensions that extend into passageways called canaliculi. |
|
|
Term
|
Definition
| aka cancellous bone, contains bony bars & plates called trabeculae |
|
|
Term
|
Definition
concentric layers of matrix where the lacunae is found.
contains collageous protein fibers & mineral deposits of mostly calcium & phosphorus cells.
|

Term
|
Definition
| unspecialized cells found in inner periosteum, endosteum, & central canal of compact bone. |
|
|
Term
|
Definition
bone-forming cells
derived from osteoprogenitor cells
responsible for secreting the matrix charactistic of bone.
|

Term
|
Definition
mature bone cells derived from osteoblasts.
|
|
|
Term
|
Definition
derived from monocytes, type of which blood cell.
Perform bone resorption; breaking down of bone and depositing of calcium & phosphate in the blood. |
|
|
Term
|
Definition
refers to the formation of bone during embryonic stage.
occurs in two ways.
1. Intramembranous
2. Endochondral |
|
|
Term
Intramembranous
ossification |
|
Definition
development of bone between sheets of fibrous connective tissue.
bones of the skull develop in this manner
Cells derived from these tissues become osteoblasts |
|

Term
Endochondral
Ossification
|
|
Definition
most of the human skeleton is formed by this process
replaces hyaline cartilage. |
|
|
Term
|
Definition
| band of cartilage between primary and secondary ossification centers |
|
|
Term
|
Definition
Osteoprogenitor cells in inner periosteum convert to osteoblast cells.
Basically, new bone created over old bone.
bones become THICKER & Harder.
