cartilaginous symphysis joints (annulus, nucleus, end plates)
|
|
facet joints are..
|
z joint, apophyseal

|
Kinematics
|
kinematics
|
|
general motions are?
|
flex, extension, rotation, lateral flexing/bending
|
|
Coupled motion (coupling)
|
the consistent association of one motion about an axis with another motion about a different axis. Most predominant are rotation & lateral flexion – in order for either to occur some of the other must also occur

the________ is determined primarily by the orientation of the _________
|
direction of motion
facets |
|
Facet joint capsule provide stability while limiting motion
