4 functions of skeletal system |
1) provides support and protection 2) assists body movement 3) participate in blood cell production 4) storage of mineral and energy reserves |
|
|
3 components to bone structure |
Diaphysis, epithysis, metaphysis |
|
|
Diaphysis |
Is the shaft of the long bone |
|
|
Epithysis |
Form proximal and distal ends of long bones |
|
|
Metaphysis |
Areas where epiphysis and diaphysis join |
|
|
7 tissues of the skeletal system |
Compact, spongy, articular, fibrocartilage, periostuem, medullary cavity and endosteum |
|
|
Compact bone |
Strongest form of bone tissue |
|
|
Spongy bone |
Located within the compact bone It supports bone marrow |
|
|
Articular cartilage |

|
|
Fibrocartilage |
Invertrbral discs and menisci |
|
|
Red bone marrow |

|
|
