Definition
|
|
Term

|
Definition
they slope inferiorly from anterior to posterior and facilitates flexion and extension |

|
Definition
vertically, they limit flexion and extension, but facilitate rotation |
|
|
Term
How are the zygapophysial joints situated in the lumbar vertebrae? |
|
Definition
joint surfaces are curved and adjacent processes interlock, thereby limiting range of movement, though flexion and extension are still major movements in the lumbar region |
|
|
Term
What is an uncovertebral joint |
|
Definition
the lateral margins of the upper surfaces of typical cervical vertebrae are elevated into crests or lips ermed uncinate processes. these may articulate with the body of the vertebra above to form small "uncovertebral" synovial joints |
