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)
guy wire
