C-Spine
What other name refers to:
C1, C2, & C7
C2: Axis
C3: Vertebral Prominens
Which bones articulate with thoracic facets and demifacets?
Ribs
What happens/is different about the bodies as you go from 1st to 5th?
Why is an AP axial projection of the coccyx preferred to the PA axial projection?
The AP projection places the coccyx closer to the IR
Solid anterior part of the vertebrae
Body
What 2 typical vertebral parts are missing from the first cervical vertebra?
Body and spinous process
What part of the rib articulates with the facet to create the costovertebral joint space?
Rib head
In which position do you place the patient to view the intervertebral foramina of the lumbar spine?
Lateral
What structure of the vertebral column articulates with both ilia?
Sacrum
Connects the transverse processes with the spinous processes
Laminae
With reference to the midsagittal plane, how do cervical intervertebral foramina open?
45 degrees anteriorly
With reference to the midsagittal plane, how do zygapophyseal articulations of the thoracic vertebrae open?
70 degrees anteriorly
What is the part of the lamina between the superior and inferior articular processes called?
Pars interarticularis
The sacrum is formed by the fusion of how many sacral vertebral segments?
Five
Articular processes
Zygapophyses
Which position of the cervical vertebral column best demonstrates the right intervertebral foramina when the central ray is angled 15 to 20 degrees?
RAO
The bodies of the second through eighth thoracic vertebrae contain (facets/demifacets) superiorly and inferiorly.
Demifacets
How many degrees and in which direction should the central ray be directed for the lateral projection of the L5-S1 when the vertebral column is positioned parallel with the table?
Perpendicular
The coccyx is composed of how many rudimentary vertebrae that typically fuse into one bone?
3 to 5 (usually 4)
Process extending laterally and posteriorly from the body
Pedicles
The ring formed by the arches is divided into anterior and posterior portions by a ligament called the
transverse atlantal ligament
Which projection most requires usage of the anode heel effect to improve its image quality?
AP projection of the thoracic vertebral column
Which positioning error most likely occurred if the zygapophyseal joints were not well demonstrated and the pedicle was quite anterior?
The patient was not rotated enough
Which projection and patient position best demonstrates the right SI joint?
AP oblique projection with the patient in the LPO projection
Correctly identify these 2 parts:
1. Process extending posteriorly from the junction of both laminae
2. Process extending laterally from the pedicle-lamina junction
1. Spinous Process
2. Transverse process
