Answer 12

distracted/ compressed

Question 13

facet during flexion

Question 14

ribs during flexion (ant / post)

Answer 14

approximate / separate

Question 15

Costo transverse joint during flexion
T1-7
8-10

Answer 15

anterior rotation and sup glide
ant rotation and PMS glides

Question 16

Costo transverse joint during extension

Question 17

Answer 18

anterior rotation (t1-10)

Question 19

total extension
segmental extension

Answer 19

25
1-2

Question 20

what UE movements cause extension

Question 21

VB during extension

Question 22

z joint facet extension

Answer 22

post / inf glides

Question 23

motion restricted by (extension)

Question 24

ant / post ribs (extension)

Answer 24

separate / approximate

Question 25

Costotransverse during extension

Answer 25

t1-7 post rot + inf glide
8-10: post rot ILA glide

Question 26

costosternal joints during extension

Answer 26

post rotation

Question 27

lateral flexion total and segmental

Answer 27

25-40
7-9

Question 28

lateral flexion VB

Answer 28

ipsi roll and glide

Question 29

lateral flexion z joint facets

Answer 29

ipsilateral: inf/post (extension)
contralateral: superior/anterior (flexion)

Question 30

lateral flexion ribs

Answer 30

ipsi approx
contra separate

Question 31

lateral flexion CT joints

Question 32

Latexion

Answer 32

rib and z joint move together in the beginning (Ipsi z joint will move down and back + rib approximation)
THEN z joint has more motion so pushes rib away

NOW: ipsi rib motion = ant rotation and sup glide
contra rib = post rot inf glide (this is why CL rot)

Question 33

lateral flexion CT joint Ribs

Answer 33

t3-t7: ipsi–ant rotation sup glide
8-10 ipsi ant rotation PMS glides

lateral flexion CS joint rib motion

Answer 34

3-8

Question 35

rotation motion total and segmental

Question 36

rotation VB motion

Answer 36

ipsi roll
contra glide

Question 37

rotation z joint motion

Answer 37

ipsilateral: inferior posterior glide
contra: superior anterior

Question 38

Rotextion coupled motion

Question 39

Rotexion CT joint

Answer 39

t3-t7: ipsi post rotation inf glide
contra
8-10: ipsi post rotattion ILA
contra

Question 40

rotexion Costo sternal joint

Answer 40

3-8:
ipsi posterior
contra: anterior

Question 41

rib motions during breathing
t1-2
3-7
8-10

Answer 41

Answer 42

1-7 superior and anterior to increase AP diameter
CV: inferior glide
8-10 ??? move PMS, glide ILA
10-12: fixed
