Spine II Flashcards
During cervical flexion, identify the roll & glide at the atlanto-occipital joint.
anterior roll, posterior glide
During cervical extension, identify the roll & glide at the atlanto-occipital joint.
posterior roll, anterior glide
During R lateral flexion, identify the roll & glide of the atlanto-occipital joint.
roll to the right, glide to the left
During R cervical rotation, identify the movement of the ROC & LOC.
ROC moves back, LOC move forward
During cervical flexion, identify the direction the atlantoaxial facets face.
forward
During cervical extension, identify the direction the atlantoaxial facets tilt.
backward
During R lateral flexion, identify the movement of the atlas at the atlantoaxial joint.
atlas “squeezed” toward the right, rotates to the left
During R cervical rotation, identify the movement of the facets at the atlantoaxial joint.
RF moves back, LF moves forward
During flexion at C2/3-T2/3, identify the movement at the facets.
RF and LF slide up & forward
During extension at C2/3-T2/3, identify the movement at the facets.
RF and LF down & back
During R lateral flexion at C2/3-T2/3, identify the movement at the facets.
RF downslide, LF upslide
During R rotation at C2/3-T2/3, identify the movement at the facets.
RF downslide, LF upslide
During flexion at T3/4-T11/12, identify the movement at the facets.
RF and LF slide up
During extension at T3/4-T11/12, identify the movement at the facets.
RF and LF slide back
During R lateral flexion at T3/4-T11/12, identify the movement at the facets.
RF slides down, LF slides up
During R rotation at T3/4-T11/12, identify the movement at the facets.
RF distracts, LF compresses and acts as fulcrum
During lumbar flexion, identify the movement at the facets.
RF and LF slide up
During lumbar extension, identify the movement at the facets.
RF and LF slide down
During R lumbar lateral flexion, identify the movement at the facets.
RF slides down, LF slides up
During R lumbar rotation, identify the movement at the facets.
RF distracts, LF compresses and acts as a fulcrum
During cervical flexion, is the force/compression anterior or posterior? What affect does this have on the IV disc? Nucleus pulposus?
Anterior force/compression
IV disc bulges posteriorly
Nucleus pulposus centered more posteriorly
During cervical flexion, does the space between SP’s increase or decrease?
Increase
What is the effect of cervical flexion on the anterior & posterior longitudinal ligament?
Anterior longitudinal ligament = slackened
Posterior longitudinal ligament = tensed/stretched
During cervical flexion, does the intervertebral foramen size increase or decrease?
Increase
