Q

lower thoracic is blank

A

t8-t12

19
Q

ribs 1-6 are blank

A

close together

20
Q

sidebending and rotation occur in the blank direction in neutral and non neutral mechanics of upper thoracic

A

same, type 2 fryettes

21
Q

sidebending and rotation occur in the blank direction in neutral mechanics of lower thoracic

A

opposite, type 1 fryettes

22
Q

lower thoracic obeys blank in non neutral positions (same side)

A

type 2 fryettes

23
Q

thoracic spine has blank degrees of freedom

A

3

24
Q

upper thoracic has decreased blank because of blank facets

A

flex/ext, frontal plane

25
Q

lower thoracic has increased blank because of blank facets

A

flex/ext, sagittal

26
Q

lower thoracic rotation from neutral, note tipping and tilting of sp toward the blank of spine (frontal plane) or blank of ribs (sagittal plane)

A

concavity, concavity

27
Q

upper thoracic rotation from neutral, note tipping and tilting of the sp toward the blank of spine and blank of ribs because ribs are pulled posteriorly

A

concavity, convexity

28
Q

an anteriorly displaced disk of the tmj would produce this

]

A

closed lock, reciprocal click

29
Q

planar, synovial joint between ribs and vertebral body

A

costovertebral joint

30
Q

t9-t12 vertebral facets are blank on pedicles

A

posterior

31
Q

ribs 2-10 also articulate with blank

A

iv disk

32
Q

cv joints are clinically tested during blank

A

rib springing

33
Q

planar synovial joints between ribs and tp

A

costotransverse joint

34
Q

costal tubercle of rib articulates with blank on tp

A

costal facet

35
Q

ct joints are for these ribs not the blank ribs

A

1-10, floating

36
Q

with inspiration, first rib elevates with blank and blank costovertebral joint motion occuring

A

superior, posterior

37
Q

t1 may blank slightly during inspiration

A

extend

38
Q

ribs 1-6 creates nearly blank plane motion around blank axis

A

frontal, m-L

39
Q

ribs 7-10 nearly is blank motion around blank axis

A

sagittal plane, a-p

40
Q

ribs 1-6 are called blank handle because it increases blank dimension and blank motion

A

pump, a-p, sagittal plane

41
Q

ribs 7-10 are called blank handle and increases blank dimension and blank motion

A

bucket, m-L, frontal plane
