| What is the difference between Suture and synostosis? |
|
Definition
| A synostosis forms when the fibrous connective tissue in a suture ossifies and the suture closes |

Term
| Describe what happens during weeping lubrication? |
|
Definition
| Weeping lubrication occurs when synovial fluid is squeezed in and out of the cartilage from the pressure of human movement. It lubricates and allows minimal friction |

| Synovial joint... Define Planar: |
|
Definition
| The bone surfaces are flat or only slightly concave and convex. |
|
|
Term
| Synovial joint... Define Hinge: |
|
Definition
| A cylindrical convex surface of one bone fits into a cylindrical depression in the other |
|
|
Term
| Synovial joint... Define Pivot: |
|
Definition
| The rounded end of a bone fits into a notch in another bone |
|
|
Term

Definition
| An oval convex surface on one bone fits into an oval shaped depression in another |
|
|
Term
| Synovial joint... Define Saddle: |
|
Definition
| The convex surface of one bone and the concave surface of the other lie 90 degrees to each other |
|
|
Term
| Synovial joint... Define Ball and Socket: |
|
Definition
| A hemispherical convex surface (the head) on one bone fits into a cup-like socket on the other |

Term
| Can 1st class levers operate at a mechanical advantage, mechanical disadvantage, or both? Explain. |
|
Definition
Both.
Mechanical advantage for power.
Mechanical disadvantage for speed and distance. |
|
|
Term
| Can 2nd class levers operate at a mechanical advantage, mechanical disadvantage, or both? Explain. |
|
Definition
Mechanical advantage.
2nd class levers act as a power lever, allowing small muscular efforts to move much larger loads |
|
|
Term
| Can 3rd class levers operate at a mechanical advantage, mechanical disadvantage, or both? Explain. |
|
Definition
Mechanical disadvantage.
3rd class levers place muscle insertions close to the joint providing stability to the joint producing fast, extensive movements, with little shortening of the muscle. |
