Flashcards in Thoracic Spine Biomechanics Part 1 Deck (41):
1

rib cage is a blank kinematic system

closed

2

thoracic spine does not need blank processes because rib attachment stabilizes them

uncinate processes

3

longer sp of thoracic vertebrae are for blank and increased blank

muscle attachment, surface area

4

thoracic spine tp are thickened for blank

rib articulation

5

inferior facets of thoracic face blank and blank

inferior/anterior

6

superior facets of thoracic face blank and blank

superior/posterior

7

increased compression at vertebral body function is to keep thoracic spine on track, not blank

bear weight

8

allows for articulation with rib

demifacet

9

demifacet articulates with costal blank

tubercle

10

zone of weakness of thoracic spine is due to a decreased blank system

trabecular

11

zone of weakness can lead to blank fracutre blank

compression, anteriorly

12

zone of weakness is a blank shape out of vertebrae

traiangular

13

trabecular system is resistant to blank and blank forces

compressive/shear

14

ribs restrict thoracic blank

ROM

15

relative increased rotation and sidebending availabe in blank thoracic

upper

16

blank thoracic is more for flexion and extension

lower

17

upper thoracic is

t1-t4

18

lower thoracic is blank

t8-t12

19

ribs 1-6 are blank

close together

20

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

same, type 2 fryettes

21

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

opposite, type 1 fryettes

22

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

type 2 fryettes

23

thoracic spine has blank degrees of freedom

3

24

upper thoracic has decreased blank because of blank facets

flex/ext, frontal plane

25

lower thoracic has increased blank because of blank facets

flex/ext, sagittal

26

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

concavity, concavity

27

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

concavity, convexity

28

an anteriorly displaced disk of the tmj would produce this
]



closed lock, reciprocal click

29

planar, synovial joint between ribs and vertebral body

costovertebral joint

30

t9-t12 vertebral facets are blank on pedicles

posterior

31

ribs 2-10 also articulate with blank

iv disk

32

cv joints are clinically tested during blank

rib springing

33

planar synovial joints between ribs and tp

costotransverse joint

34

costal tubercle of rib articulates with blank on tp

costal facet

35

ct joints are for these ribs not the blank ribs

1-10, floating

36

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

superior, posterior

37

t1 may blank slightly during inspiration

extend

38

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

frontal, m-L

39

ribs 7-10 nearly is blank motion around blank axis

sagittal plane, a-p

40

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

pump, a-p, sagittal plane

41

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

bucket, m-L, frontal plane
