|
Definition
| When a broken bone breaks through the skin |
|

Term
| Which type of injury is more serious, a simple fracture or a compound fracture |
|
Definition
| A compound fracture. When the bone breaks through the skin, it increases the risk of infection |

|
Definition
| A blood clot forms, then a mass of soft tissue called a callus forms; it is made of cartilage. This callus is transformed into spongy bone and then strong compact bone. |

| What are the 5 functions of the skeletal system? |
|
Definition
Allows for movement - with muscles
Shapes and supports the body
Protects internal organs
Forms blood cells
Stores mineral reserves |
|
|
Term
| How many bones are in the adult human skeleton |
|
Definition
|
|
Term
| Do infants have more or fewer bones that adults? |
|
Definition
| Infants have more bones because as they grow, some of their bones fuse together - think skull! |

Term
| How do bones help the body maintain homeostasis? |
|
Definition
| They store mineral reserves. When these minerals are needed, they can be released from bone tissue. When mineral levels in the body are high, they can be stored in bone. |
