1
Q

Anterior Longitudinal L.

A

ALL, C2 to sacrum
widest at sacrum, blends with discs
only spinal l. that resists (hyper)extension

2
Q

Posterior Longitudinal L.

A

PLL, C2 to sacrum

widest at sacrum, resists flexion, fans out at discs

3
Q

Capsular ll.

A

at each zygapophyseal joint, C2 to sacrum

flexible, includes meniscoids (synovial folds)

4
Q

Interspinous ll.

A

C2 to sacrum, discontinuous,

b/w S.P.s, poorly developed except in lumbar

5
Q

Intertransverse ll.

A

C2 to sacrum, discontinuous

b/w T.P.s, poorly developed except in lumbar

6
Q

Ligamentum Flavum

A

C2 to sacrum, left & right sides
discontinuous, connecting laminae of segments
thick, touch, yellow, b/c of elastic fibers; resists flexion & absorbs shock
helps posterior wall of v. canal & posterior mm. to maintain erect posture

7
Q

IVD

A

C2 to sacrum,

intervertebral disc itself is a ligament

8
Q

Transforaminal L.

A

C2 to sacrum, variable in size (and presence)

reduces size of IVF

9
Q

Anterior Antlantooccipital L.

A

homologous to the ALL from occiput to C1

10
Q

Posterior Atlantoccipital L.

A

homologous to Ligamentum Flavum between occiput & C1

has arcuate foramen for vertebral artery

11
Q

Lateral Atlantoccipital L.

A

later mass of atlas to paramastoid process (C1 to occiput)

12
Q

Anterior Atlanto-axial L.

A

homologous to ALL b/w C1 to C2

13
Q

Posterior Atlanto-axial L.

A

homologous to Ligamentum Flavum, b/w C1 to C2

14
Q

Accessory L.

A

lateral mass of C1 to posterior body of C2, deep to tectorial membrane

15
Q

Tectorial L.

A

homologous to PLL, b/w C2 to occiput, along anterior border of foramen magnum

16
Q

Cruciform L.

A

deep to tectorial membrane, holds dens against facet; transverse part attaches to lateral masses and holds dens in place; longitudinal part connects to anterior border of foramen magnum (occiput) to body of C2

17
Q

Alar L.

A

paired, attach dens to left & right occipital condyles (alar tubercles), occiput to C2

18
Q

Supraspinous L.

A

C7 to sacrum, continuous, connecting SPs

19
Q

Nuchal l.

A

parts: funicular cord (to EOP) and lamellar membrane (to median nuchal line)
connecting all SPs in cervical region, homologous to supraspinous l.

20
Q

Costovertebral articular capsule l.

A

thoracic only

21
Q

Costovertebral interosseous l.

A

thoracic

attaches crest of rib head to IVD, separates joint cavity into superior/inferior halves

22
Q

Radiate l.

A

thoracic region
superior/intermediate/inferior bands
connect to body above/disc/body below

23
Q

Costotransverse articular capsule l.

A

thoracic region

24
Q

Costotransverse interosseous l.

A

thoracic
from costal neck to base of T.P.
(the rib neck l.)

25
Q

Lateral costotransverse l.

A

thoracic region

tip of T.P. to costal tubercle

26
Q

Superior costotransverse l.

A

thoracic region

neck of rib to T.P. of segment above

27
Q

Superior iliolumbar l.

A

TP of L4 to iliac crest

lumbosacral - support flex/ext & lateral flexion

28
Q

Inferior iliolumbar l.

A

TP of L5 to iliac crest

lumbosacral - support flex/ext & lateral flexion

29
Q

Lumbosacral l.

A

L5 T.P. to sacral ala

support flex/ext & lateral flexion

30
Q

Posterior sacroiliac l.

A

sacrum to pelvis

quite strong, extensive; short horizontal fibers & long vertical fibers; prevents sacrum from falling b/w ilia

31
Q

Anterior sacroiliac l.

A

sacrum to pelvis

very strong, less significant than & deep to post SI l.; reinforces anterior SI capsule, blends to capsule

32
Q

Interosseous sacroiliac l.

A

sacral tuberosity to ilial tuberosity

very strong, located deep/anterior to posterior SI l.

33
Q

Sacrotuberous l.

34
Q

A

ischial spine (of pelvis) to anterior sacrum
