1

where does the anterior longitudinal ligament extend from?

anterior surface of vertebral bodies

2

can you stress the anterior longitudinal ligament?

No, taugt extension, can't in reality stress it

3

what aspects of the anterior longitudinal ligament are broader, thinner?

broader caudally and thinner cranially

4

at about the level of C2 what is the anterior longitudinal ligament replaced by?

it is replaced by the anterior atlantooccipital membrane (different type of tissue)

5

the anterior longitudinal ligament is thicker and narrower in the _spine than in the _ and _ spine

thicker and narrower in the T-spine than in the c and l-spine

6

the anterior longitudinal ligament extends to the front of the ___

sacrum

7

the longitudinal fibres of the anterior longitudinal ligament attach to what?

IVD

hyaline cartilage

anterior aspect of vertebral bodies 

8

the anterior longitudinal ligament fibres blend with what?

subadjacent periosteum, perichondrium and periphery of the annulus fibrosis

9

describe the anterior longitudinal ligament superficial layer

longest, extend over 3 of 4 vertebrae (thinnest, weakest)

10

How many vertebrae does the anterior longitudinal ligament intermediate layer run between?

between two or three vertebrae

11

describe the anterior longitudinal ligament deep layer

one body to next (strongest)

12

where does the posterior longitudinal ligament lay?

lies in the vertebral canal on the posterior surface of the vertebral bodies

13

what is the posterior longitudinal ligament continuous with at about C1-C2?

membrane tectoria

14

what does the posterior longitudinal ligament attach to?

IVD, hyaline cartilage and vertebral bodies

15

in the lumbar spine and lower thoracis spine the posterior longitudinal ligment is ___, narrow over ___ and broad over ___

in lumbar spine and lower thoracic spine it is DENTICULATE, narrow over VERTEBRAL BODIES and broad over DISCS

16

what is the posterior longitudinal ligament fused with and how does this reinforce the disc

fused with nulus fibrosis of the IVD therfore reinforces disc posteriorly

17

when is the posterior longitduinal ligament taut?

in flexion

18

T/F the posterior longitudinal ligament is affected by anything in the vertebral canal i.e. meningitis, disc herniation

TRUE

19

describe the superficial layer of the posterior longitudinal ligament

longest, extend over 3 of 4 vertebrae

20

describe the intermediate layer of the posterior longitudinal ligament

between two or three vertebrae

21

describe the deep layer of the posterior longitudinal ligament

extends between adjacent vertebrae

22

where is the ligamentum flavum found and what does it lie posterior to?

inside vertebral canal posterior to spinal cord

23

what does the ligamentum flavum connect in the vertebral canal?

connects lamina to lamina

24

what tissue properties does the ligamentum flavum have and what does this allow for?

yellow elastic tissue like the ligamentum nuchae to allow for mobility and recoil

25

what does the ligamentum flavum restrict and what does it provide rebound tension for?

restricts flexion and lends rebound tension to go back into extension

26

do the fibres of the ligamentum flavum run parallel or perpendicular?

almost perpendicular fibres

27

what two points does the ligamentum flavum run between?

descend from inferior surface of one lamina to the superior surface of next lower lamina

28

where is the ligamentum flavum thin, thick and thickest?

thin -broad and long in the neck

thicker - in the thoracic spine

thickest -in the lumbar spine

29

what is the most superficial ligament in the spine?

surpraspinous ligament

30

what points does the supraspinous ligament run between

from spinous process to spinous process - C7 to sacrum (becomes ligamentum nuchae above C7)
