IVF Flashcards
range for cervical
30-45 degrees
range for lumbar
34-45 degrees
what is the smallest ivf
cervical
size of cervic al ivf
5mm
angle of cervical ivf
anterolaterally and slightly inferiorly
where are cervical ivf found
only between vertebrae that have discs between them
there are no cervical ivf betwen
occiput and c1, c1 and c2
nerves exit () to z joint when it comes to oc-c1 adn c1-c2
posteriorly
c3 and down the nerves exit () to z jt
anteriorly
largest ivf
lumbar
up to () mm at L5-S1
18 mm
lumbar and thoracic ivf face
laterally /straight out
6 boundaries of ivf for lumbar and cervical
- inferior notch: superior border
- superior notch: inferior border
- ivd
- body of vertebrae BOTH
- articulating process
- zygopophyseal jt
superior vertebral notch of pedicles of thoracic are completely flat compared to ()
inferior vertebral notch
the consequence of the flat sup vert notch is that the
posterolateral aspect of bodies below does NOT CONTRIBUTE TO IVF
boundaires of thoracic vert
- body of vert ABOVE
- ivd between 2
- inferior vertebral nothch
- superior vert notch
- zygopophyseal jt
where does the lumbar nerve sit in the ivf
upper portion
where does the thoracic nerve sit in the ivf
middle portion
where does the cervical nerve sit in teh ivf
lower portion
where does spinal cord end in adult and child
l2 in adult, l4 child
contents of ivf (9)
- true spinal nerve trunk surrounded by 3 meninges
- dorsal root ganglion (sensory)
- spinal artery- corresponding segmental a in that area (vertebral, intercostals, lumbar)
a. anterior branch
b. posterior branch
c. neurospinal artery of KADYI - anterior and posterior redicular veins
- dural root sleeve (encloses the neuropsinal artery of KADYI
- the recurrent meningeal nerves
- the intervertebral veins
- lymphatic channels which run along vertebral venous plexus
- adipose tissue
the neurospinal artery of kadyi divides into
anterior and posterior radicular arteries
the neurospinal artery of kadyi travels with the
nerve roots
the intervertebral veins communicate between the
INTERNAL verbral and EXTERNAL vertebral venous plexus
the internal and external vertebral venous plexus is at () and drains into ()
posterior aspect of body and drain into basilar v
the lymphatic channels run along
vertebral venous plexus
