Q

Behind the eye head aches are often attributed to the ________ nerve, which pierces through the _________ and ________ to get to its position around the eyes. It may also be associated with C__-C__ vertebrae.

A

Behind the eye head aches are often attributed to the GREATER OCCIPITAL nerve, which pierces through the TRAPEZIUS and SEMISPINALIS CAPITUS to get to its position around the eyes. It may also be associated with C2-C3 vertebrae.

8 pairs
28
The spinal nerves have the largest _____ of the spine
Dorsal roots
29
Which nerves make up the ansa cervicalis?
C1 C2 C3
30
What is the trigeminal- cervical nucleus?
The gray matter migrates into the spinal cord, disturbing CN V (trigeminal n), C1, C2, and C2. This intermingling of efferent information may manifest as sensory pain to the face.
31
True or false; there is evidence to support cervical mobility has an impact on vertebral artery flow
False
32

33
True or false; C1 tension and torque can block blood blow of the internal carotid artery
True
34
What percentage of weight bearing do the facet joints perform? The disc?
Facets - 40% | Discs- 60%
35
When one refers to the tripodism of a vertebrae, to what are they referring?
The joints; 2 facets and 1 disc
36
Tell me about the intra-articular menisci
``` ⦿ Cranial/Caudal ◼present in C-T-L spine ◼ provide stability ◼ Load distribution in facet joints ◼ Ligamentum Flavum is an attachment for the disc ◼ Impingement source ```
37
Where are the joints of von Luschka found?
C3-C7
38
What is the purpose of the joints of von Luschka?
Assist congruency Safety stopper Limit excessive lateral flexion
39
The joints of von Luschka are prone to ___________ changes.
Spondolytic
40
What are the 2 main components of the intervertebral discs?
Annulus fibrosis | Nucleus pulposis
41
Where is a spinal segment most stable?
Optimal Zone of Load
42
What is the Rule of Superior Motion?
Motion of a single vertebra is described relative to the vertebra below regardless of whether the motion occurs from above down or below up
43
What is the rule of vertebral body motion?
It is the direction of the vertebral body and not the spinous process that determines the direction of vertebral motion
44
Roll-Gliding occurs between _________________ during all active and passive rotations
incongruent curved joint surfaces
45
_________: Occurs when a new point on one surface always comes into contact with a new point on the other surface
Roll
46
________: Occurs when one point on one surface always comes into contact with a new point on the other surface
Glide
47
Which actions roll around the x axis

48
Which actions roll around the z axis?
Side bending
49
Which actions roll around the Y axis?
Rotation
50
Which directions translate along the x axis?
Medial and lateral
51
Which directions translate along the z axis?
Anterior posterior

Which directions translate along the y axis?
Cranial caudal

CO-C1-C2 follow _______ rule; roll- glide occur in _____ directions
Convex | Opposite
54
C2-C3 to L5-S1 follow _______ rule; roll- glide occur in _____ directions

55
What is fryette's first rule?
When the vertebrae are idling in neutral (ie., facets are unloaded), side bending is associated with contralateral rotation
