ANSWER intervertebral foramina
which radiographic position best demonstrates the structure identified in
the previous question - ANSWER lateral position
the small foramina found in the sacrum are called - ANSWER pelvic
sacral foramina
the anterior and superior aspect of the sacrum that forms the posterior
wall of the pelvic inlet is called the - ANSWER promontory
what is another term for the sacral horns - ANSWER cornua
the sacroiliac joints lie at an oblique angle of ______ degree to the
coronal plane - ANSWER 30 degree
what is the formal term for the "tail bone" - ANSWER coccyx
what is the name for the superior broad aspect of the coccyx - ANSWER
base
zygapophyseal classification, mobility, and movement - ANSWER
synovial, diathrodial, plane or gliding
intervertebral classification, mobility, and movement - ANSWER
cartilaginous, amphiarthrodial (slightly movable), none
left posterior oblique - ANSWER left zygapophyseal joints
, right posterior oblique - ANSWER right zygapophyseal joints
right anterior oblique - ANSWER left zygapophyseal joints
left anterior oblique - ANSWER right zygapophyseal joints
lateral - ANSWER intervertebral foramina
the degree of obliquity required for an oblique projection at the T12-L1
level is aprrox. _____, wheras the L5-S1 level spine requires a _____
oblique. therefor a ______ oblique is performed for the general lumbar
spine - ANSWER 50 degree, 30 degree, 45 degree
ASIS - ANSWER S1-S2
xiphoid process - ANSWER T9-T10
lower costal margin - ANSWER L2-L3
illiac crest - ANSWER L4-L5
symphysis pubis - ANSWER tip of coccyx
true/false placing a lead blocker mat behind the patient for lateral lumbar
spine positions improves image quality - ANSWER true
true/false the use of higher kV and lower mAs for lumbar spine
radiography improves radiographic contrast but increase patient dose -
ANSWER false
true/false the A.P projection of the lumbar spine opens the intervertebral
joint spaces better than the PA proj - ANSWER false (PA would open
intervertebral joint spaces better)
true/false gonadal shielding should always be used for male and female
patients for studies of the lumbar spine - ANSWER false (not used for
females if the shield would obscure essential anatomy)
