Q

A typical vertebra, is composed of what two main parts?

A

Anterior mass called the body and a posterior ringlike portion called the vertebral arch

  • Body and Vertebral Arch
22
Q

The vertebral body and arch enclose a space called?

A

Vertebral foramen

23
Q

What forms the vertebral canal?

A

vertebral foramina

24
What separates the vertebral bodies?
Intervertebral disks
25
What forms the vertebral arch?
2 pedicles and 2 laminae
26
What projects laterally and slightly posteriorly form the junction of the lamina?
Transverse process
27
What vertebra is a ring-like structure with no body and a very short spinous process?
Atlas - C1
27
What projects posteriorly and inferiorly from the junction of the lamina?
Spinous process
28
What vertebra has a strong conical process arising from its upper surface?
Axis - C2
29
What vertebra has a long prominent process that projects almost horizontally to the posterior?
C7 - vertebral prominins
30
What type of vertebrae have small, transversely located, oblong bodies with slightly elongated antero-inferior borders?
Typical cervical vertebrae
31
What projection of the c-spine will show the IVF (intervertebral foramen)?
Oblique
32
What projection of the T-Spine will show the IVF (intervertebral foramen)?
Lateral
33
What projection of the c-spine will show zygapophyseal joints?
Lateral
34
For an AP open-mouth projection, how do you adjust the head?
Aligned from the lower edge of the incisors to the tip of the mastoid process is perpendicular to the IR
35
How will having the patient phonate "ah" during the exposure place the tongue?
The floor of the mouth
36
Where is the CR for an AP open-mouth projection?
Perpendicular to IR and entering at midpoint of open mouth
37
How do you know when the position for an AP open-mouth cannot be improved?
When the upper central incisors and the base of the skull are in line with those of the tips of the mastoid processes
38
For an AP axial projection of the c-spine, how do you position the patient?
Extend the chin so the occlusal plane is perpendicular to the tabletop so that the mandible is out of the way of the base of the skull
39
Where do you center the IR for an AP axial c-spine? Is there a tube angle?
C4 at an angle of 15-20 degrees cephalad
40
Why do we angle the CR for an AP axial projection?
It opens the intervertebral disk spaces
41
What is the method name for a lateral c-spine?
Grandy Method
42
How do you position the patient for a lateral c-spine?
Standing, with the shoulder against IR and the long axis parallel to the IR Adjust until IR is centered at the level of C4
43
Where will the top of the film be for a lateral c-spine?
1 inch above the external acoustic meatus (EAM) (Ear Canal)
44
Where is the CR for a lateral c-spine?
Perpendicular to C4
45
For an AP axial oblique projection of the c-spine, how do you position the patient's body?
Facing away from the IR at a 45-degree angle The C spine should be aligned at the midline of the IR
46
What does elevating or protruding the chin prevent?
It prevents the mandible from overlapping the spine
47
Where is the CR for an AP axial oblique of the c-spine? Is there a tube angle?
At C4 with a 15-20 cephalad angle
48
What is shown on an AP axial oblique projection of the c-spine
IVF and pedicles farthest from the IR, as well as an oblique projection of the cervical vertebrae
49
What are some eval criteria for an AP axial oblique projection of the c-spine?
