Flashcards in Cervical Spine Biomechanics - 2 Deck (69):
1

atypical cervical vertebrae

1,2

2

typical cervical vertebrae

3-6

3

cervical vertebrae bodies are blank for blank instead of blank

small, mobility, stability

4

balance between mobility and stability

transegrity

5

cervical spine has a general laxity to blank and blank

capsule, ligaments

6

uncinate processes are not present when blank

born

7

uncovertebral joints are aka

joints of vonluschka

8

skeletal muscles near C6, osteophytes near C5, and gliding at AA can compromise blank

vertebral artery

9

extension and rotation causes a blank in blood flow

bilateral decrease

10

C1 is aka

cradle

11

c1 structure for weight bearing

lateral masses

12

oa joint is blank

planar

13

inferior facets of atlas are slightly blank

convex

14

oa rotation... both condyles are going blank but sliding blank

superior, opposite (anterior/posterior)

15

superior facets of lateral zygo joints are blank in c2

convex

16

inferior facets face blank in C2

medial

17

aa joint has blank joints

3

18

1 blank aa joint

pivot

19

2 blank aa joints

planar

20

ligament that restrains aa flexion/extension

transverse ligament

21

amount of flexion/extension at aa

zero

22

aa joint is blank on blank

convex-convex

23

rotation of aa causes one side to be blank and blank while the other is blank and blank

inferior/anterior, posterior/inferior

24

rotation of aa could go superior depending on the blank

starting position

25

c2 and c3 junction is aka blank

the root

26

fryette's law is actually a blank

theory

27

blank fryettes laws

3

28

rotation and sidebending to opposite sides are blank

fryettes law 1

29

rotation and sidebending to same sides are blank

fryettes law 2

30

typical cervical vertebrae have blank properties

meniscoid

31

impingement of meniscoid contact lens then it could refer pain and be blank classified

derangement

32

innervation to capsules of typical vertebrae and can cause referred pain

posterior rami C2-C8

33

first iv disc of cervical spine

C3-C4

34

adults do not have the blank component of cervical iv discs

gelatinous

35

lumbar discs have blank but cervical discs dont

concentric annulus

36

cervical pain cannot arise from blank fissures in the blank since there is no blank anulus fibrosus in a cervical disc

posterolateral, anulus fibrosus, posterolateral

37

discogenic pain of cervical is more caused by blank or tears of the blank anulus fibrosus or blank ligament

strain, anterior, PLL

38

how can we sb left and rotate right in cervical spine in typical vertebrae

aa joint comes into play for rotation

39

fryette's law applies to typical vertebrae in sagittal plane blank and blank

neutral, nonneutral

40

right sidebending of oa, blank and blank glide on blank side

posterior, inferior, ipsilateral

41

right sidebending of oa, blank and blank glide on blank side

anterior, superior, contralateral

42

sidebending is like blank on the ipsilateral side and blank on the contralateral side

extension, flexion

43

right rotation of aa joint makes blank/blank on ipsilateral side and blank/blank on contralateral side

posterior/inferior, anterior/superior

44

most cervical flexion/extension comes from these vertebrae

c4-c6

45

these two ligaments separate the dens from the spinal cord by creating posterior and anterior portions of the atlas

transverse, atlantal cruciform

46

vertical fibers of transverse ligaments connect blank and blank

axis, occiput

47

paired ligament attaching dens to medial occiput

alar

48

alar ligament is taut during blank but lax during blank

flexion, extension

49

alar ligament helps prevent blank displacement of c1 on c2

anterior

50

whiplash occurs in blank milliseconds

400

51

alar ligament also helps prevent blank

contralateral rotation

52

whiplash creates blank because axis of rotation moves blank

compression, up

53

disk protrusions are when the annular fibers are blank

intact

54

disk protrusion that is usually laterally

localized annular bulge

55

disk protrusion that is usually posterior

diffuse annular bulge

56

disk prolapse is when annular fibers are blank

disrupted

57

disk prolapse is when blank has migrated through the inner laminar layer but still contained

nucleus

58

disk extrusion has annular fibers blank

disrupted

59

nucleus breaks through the outermost layer

disk extrusion

60

nucleus separates from disk and goes into spinal or iv canal

disk sequestration

61

disk sequestration has annular fibers blank

disrupted

62

straight compression forces will damage blank

vertebral endplate

63

extensors of head/neck are referred to as blank muscles

suboccipital ghost

64

obliquus capitis superior action

extend/sb ipsilateral

65

obliquus capitis inferior action

rotate atlas ipsilateral

66

rectus capitis posterior minor and major action

extend/rotate ipsilaterally

67

semispinalis capitis action

contralateral rotation (uni), extension (bi)

68

splenius capitis/cervicis action

ipsilateral sb (uni), extension (bi)

69

effect where two muscles oppose each other to keep head in neutral position in good posture (allows balance)
