All functions of the Skeletal System |
Framework, movement, protection, storage, and production of blood |
|
|
Comminuted |
Bone breaks into many fragments |
|
|
Compression |
Bone is crushed |
|
|
Depression |
Broken bone portion is pressed inward |
|
|
Impacted |
Broken bone ends are forced into each other |
|
|
Spiral |
Ragged break occurs when excessive twisting forces are applied to a bone |
|
|
Greenstick |
Bone breaks incompletely, much in the way a green twig breaks |

First stage of bone fracture repair |
Hematoma forms- blood vessels ruptured and swirling curves bone cells deprived of nutrients die |
|
|
Second stage of bone fracture repair |
A fibrocartilage callus forms- new capillaries into clotted blood at sight of the damage grow and disposal of dead tissue occurs connective tissue cells form a mass of repair tissue and close gaps |
|
|
Third stage of bone fracture repair |
A bony callus forms- fibrocartilage callus is gradually replaced by bony callus which is made of spongy bone |
|
|
Fourth stage of bone fracture repair |
Bone remodeling occurs- bony callus is remodeled so it forms a strong permanent patch |
|
|
Where do you find yellow marrow? |
Medullary cavity |
|
|
What type of bone is arranged in concentric layers? |
compact bone |
|
|
Where do you find red marrow? |
Cancellous bone |
|
|
What is the end of the bone called? |
Epiphysis |
|
|
Spongy bone is also called |
Cancellous bone |
|
|
Epiphysis |
Found at the ends of the bone, has a thin layer of compact bone, while internally the bone is cancellous, capped with articular cartilage |
|
|
Epiphysial Line |
Also called the growth plate, found on both ends of the long bone |
|
|
Diaphysis |
The shaft of the long bone, has compact bone with a central cavity. |
|
|
Articular Cartilage |
Found on the ends of long bones, it is smooth, slippery, and bloodless. |
|
|
Periosteum |
A vascular, sensitive life support covering for bone. It provides nutrient-rich blood for bone cells and is a source of bone-developing cells during growth or after a fracture. The outermost layer |
|
|
Cancellous Bone and Marrow |
Found mainly within the epiphysis and has a textured appearance. Red marrow packs the spaces between beams |
|
|
Compact Bone |
A dense bone found in the diaphysis, its repeated pattern is arranged in concentric layers of solid bone tissue. The compact bone can be seen as the layer just underneath the periosteum |
|
|
Medullary Cavity, Yellow Marrow |
Of the diaphysis, serves to lighten bone weight and provide space for marrow. Yellow marrow is associated with fat |
|
|
Nutrient Artery |
Each long bone contains a tunnel in its shaft for the passage of a nutrient artery, which supplies the shaft. The artery can also be seen within the medullary cavity as branches. |
