45 degrees left or right
37
What is the acronym of cervical obliques
Caspo
38
What does caspo stand for
Cervical anterior same posterior opposite
39
CASPO is used for what
Determining IVFs of cervical
40
What is coupling motion
2 or more motions occurring at the same time
41
What occurs to SP and vertebral bodies when c spine is laterally flexed
SP will move to opposite side (contralateral and side of convexity) and bodies will move to same side as head moving (ipsilateral, concavity)
42
The brain receives blood from what two main arterial sources
Vertebral arteries (2) and carotid arteries (2)
43
The vertebral artery supplies blood to what part of brain
Posterior 1/3
44
The carotid arteries supplies blood to what part of brain
Anterior 2/3
45
What artery is the first artery off the subclavian artery
Vertebral artery
46
Subclavian artery comes off of what
Aorta
47
When the vertebral artery comes off the subclavian artery and it ascend through what
The foramina tansversarii of the first 6 vertebrae
48
After the vertebral artery goes through C-1, it turns sharply back medially and goes through what
The sulcus arteries vertebrialis and into the spinal canal
49
What happens after vertebral artery goes into the spinal canal
Unites with the other vertebral artery on opposite side and forms the basilar artery
50
How is the vertebral artery “fixed to adjacent structures” by means of
Collagen along its entire course
51
What happens to the vertebral artery due to the collagen when the C spine is rotated (30 to 45 degrees)
It will elongate
52
The vertebral artery has how many parts
4
53
Part one of the vertebral artery

54
Part two of vertebral artery
As it goes from C6 and passes through C2
55
Part three of the vertebral artery
C2 to C1, moves laterally 45 degrees and passes through C1 TVP then turns medially and goes through the sulcus arterii vertebrialis. Ponticulus posticus
56
Part four of the vertebral artery
Goes through posterior Atlanto-occipital ligament into spinal canal then joins up with fellow on opposite side to form basilar artery
57
What is VBAI
