Answer 3

roll to the right, glide to the left

Question 4

During R cervical rotation, identify the movement of the ROC & LOC.

Answer 4

ROC moves back, LOC move forward

Question 5

During cervical flexion, identify the direction the atlantoaxial facets face.

Answer 5

forward

Question 6

During cervical extension, identify the direction the atlantoaxial facets tilt.

Answer 6

backward

Question 7

During R lateral flexion, identify the movement of the atlas at the atlantoaxial joint.

Answer 7

atlas “squeezed” toward the right, rotates to the left

Question 8

Answer 10

RF and LF down & back

Question 11

During R lateral flexion at C2/3-T2/3, identify the movement at the facets.

Answer 11

RF downslide, LF upslide

Question 12

Answer 12

RF downslide, LF upslide

Question 13

During flexion at T3/4-T11/12, identify the movement at the facets.

Answer 13

RF and LF slide up

Question 14

During extension at T3/4-T11/12, identify the movement at the facets.

Answer 14

RF and LF slide back

Question 15

During R lateral flexion at T3/4-T11/12, identify the movement at the facets.

Answer 15

RF slides down, LF slides up

Question 16

During R rotation at T3/4-T11/12, identify the movement at the facets.

Answer 16

RF distracts, LF compresses and acts as fulcrum

Question 17

During lumbar flexion, identify the movement at the facets.

Answer 17

RF and LF slide up

Question 18

During lumbar extension, identify the movement at the facets.

Answer 18

RF and LF slide down

Question 19

During R lumbar lateral flexion, identify the movement at the facets.

Answer 19

RF slides down, LF slides up

Question 20

During R lumbar rotation, identify the movement at the facets.

Answer 20

RF distracts, LF compresses and acts as a fulcrum

Question 21

During cervical flexion, is the force/compression anterior or posterior? What affect does this have on the IV disc? Nucleus pulposus?

Answer 21

Anterior force/compression

IV disc bulges posteriorly

Nucleus pulposus centered more posteriorly

Question 22

During cervical flexion, does the space between SP’s increase or decrease?

Answer 22

Increase

Question 23

What is the effect of cervical flexion on the anterior & posterior longitudinal ligament?

Answer 23

Anterior longitudinal ligament = slackened
Posterior longitudinal ligament = tensed/stretched

Question 24

During cervical flexion, does the intervertebral foramen size increase or decrease?

Answer 24

Increase

Question 25

During cervical extension, is the force/compression anterior or posterior? What affect does this have on the IV disc? Nucleus pulposus?

Answer 25

Posterior force/compression

IV disc bulges anteriorly

Nucleus pulposus centered more anteriorly

Question 26

During cervical extension, does the space between SP’s increase or decrease?

Answer 26

Decrease

Question 27

What is the effect of cervical extension on the anterior & posterior longitudinal ligament?

Answer 27

Anterior longitudinal ligament = tensed/stretched
Posterior longitudinal ligament = slackened

Question 28

During cervical extension, does the intervertebral foramen size increase or decrease?

Answer 28

Decrease

Question 29

During lateral cervical flexion where is the force/compression? What affect does this have on the IV disc? Nucleus pulposus?

Answer 29

Compression/force on side toward the movement

IV disc bulges on opposite side of movement

Nucleus pulposus on opposite side of movement
