Flashcards in IVF Deck (26):
1

range for cervical

30-45 degrees

2

range for lumbar

34-45 degrees

3

what is the smallest ivf

cervical

4

size of cervic al ivf

5mm

5

angle of cervical ivf

anterolaterally and slightly inferiorly

6

where are cervical ivf found

only between vertebrae that have discs between them

7

there are no cervical ivf betwen

occiput and c1, c1 and c2

8

nerves exit () to z joint when it comes to oc-c1 adn c1-c2

posteriorly

9

c3 and down the nerves exit () to z jt

anteriorly

10

largest ivf

lumbar

11

up to () mm at L5-S1

18 mm

12

lumbar and thoracic ivf face

laterally /straight out

13

6 boundaries of ivf for lumbar and cervical

1. inferior notch: superior border
2. superior notch: inferior border
3.ivd
4.body of vertebrae BOTH
5.articulating process
6.zygopophyseal jt

14

superior vertebral notch of pedicles of thoracic are completely flat compared to ()

inferior vertebral notch

15

the consequence of the flat sup vert notch is that the

posterolateral aspect of bodies below does NOT CONTRIBUTE TO IVF

16

boundaires of thoracic vert

1. body of vert ABOVE
2. ivd between 2
3. inferior vertebral nothch
4.superior vert notch
5. zygopophyseal jt

17

where does the lumbar nerve sit in the ivf

upper portion

18

where does the thoracic nerve sit in the ivf

middle portion

19

where does the cervical nerve sit in teh ivf

lower portion

20

where does spinal cord end in adult and child

l2 in adult, l4 child

21

contents of ivf (9)

1. true spinal nerve trunk surrounded by 3 meninges
2. dorsal root ganglion (sensory)
3. spinal artery- corresponding segmental a in that area (vertebral, intercostals, lumbar)
a. anterior branch
b. posterior branch
c. neurospinal artery of KADYI
4. anterior and posterior redicular veins
5. dural root sleeve (encloses the neuropsinal artery of KADYI
6. the recurrent meningeal nerves
7. the intervertebral veins
8. lymphatic channels which run along vertebral venous plexus
9. adipose tissue

22

the neurospinal artery of kadyi divides into

anterior and posterior radicular arteries

23

the neurospinal artery of kadyi travels with the

nerve roots

24

the intervertebral veins communicate between the

INTERNAL verbral and EXTERNAL vertebral venous plexus

25

the internal and external vertebral venous plexus is at () and drains into ()

posterior aspect of body and drain into basilar v

26

the lymphatic channels run along

vertebral venous plexus
