1

The raised ridges along the lateral sides of the superior vertebral plateau are from the ____

The raised ridges along the lateral sides of the superior vertebral plateau are from the *uncinate processes*

2

The uncinate processes from the superior and inferior vertebral form ___

The uncinate processes from the superior and inferior process form *unciform joints*

3

Why aren't unciform joints considered synovial?

They lack hyaline cartilage, subcontral bone, synovium and a joint capsule

4

Where does the facet/ZPJ joints of the superior vertebra face?

Upwards and backwards

5

Where does the facet/ZPJ joints of the inferior vertebra face?

Forward and downward

6

ZPJ’s together with the uncovertebral Joints
considered to make an important contribution to stability by ___ and thereby, protecting the IVD from severe torsion strain

ZPJ’s together with the uncovertebral Joints
considered to make an important contribution to stability by *restraining excessive movement* and thereby, protecting the IVD from severe torsion strain

7

ZPJ’s in ____ spine do not protect IVD as much as they do in ___ Spine

ZPJ’s in *Cervical* spine do not protect IVD as much as they do in *Lumbar* Spine

8

The uncovertebral/unciform joints are also known as the ___ or the ___

The uncovertebral/unciform joints are also known as the *Joints of Luschka or the lateral interbody joints*

9

The Uncinate processes grow upwards
from the ___ aspect of each lateral
vertebral margin towards the vertebral
body above

The Uncinate processes grow upwards
from the *superior* aspect of each lateral
vertebral margin towards the vertebral
body above

10

The uncinate processes grow from the ___

The uncinate processes grow from the * loose vascular fibrous tissue lateral to the annulus*

11

The uncinate processes have grown enough by age 7 – 8 yrs to form a sort of ____ on each side of the disc

The uncinate processes have grown enough by age 7 – 8 yrs to form a sort of *adventitious joint (UV joint)* on each side of the disc

12

UV joint lined by ___ and a thin
fibrous “capsule” limits each joint cleft
laterally

UV joint lined by *fibrocartilage* and a thin
fibrous “capsule” limits each joint cleft
laterally

13

From what level to what level does the uncovertebral joints build up?

From C3-C7

14

True or false

UV joints do not have synovial fluid

True

15

True or false

UV joints have interstitial fluid around the
joint and surrounding surfaces

True

16

Why does the stability of the cervical spine depends on the integrity of the ZPJ, posterior musculature and ligaments?

Arrangement of these UV joints not seen
as adding stability to the C spine, hence,
stability more dependent upon integrity
of ZPJ’s and posterior musculature and
ligaments

17

The most important aspect of the UV joint is it’s effect on the ___

The most important aspect of the UV joint is it’s effect on the *development of the cervical IVD*

18

As the uncus starts to grow the disc begins
to ___

As the uncus starts to grow the disc begins to *‘split’ and ‘fissure*

19

Formation of UV joints effectively narrows ___ within which translatory movements accompanying flexion take place

Formation of UV joints effectively narrows *horizontal band* within which translatory movements accompanying flexion take place

20

Presence of the UV joints results in ____ into the annulus from the UV joints

Presence of the UV joints results in *medial extension of horizontal fissures* into the
annulus from the UV joints

21

Where does C2 disc refer pain to?

Only disc that refers pain superiorly into the head – may be common source of headaches

22

Where does C5, C6 and C7 discs refer pain t?

Lower motion segments – refer into the UE and usually proximal to elbow

23

Characteristically – pain spreads in a line on the ___ and or ___ aspect of the upper arm in and around the triceps muscles

Characteristically – pain spreads in a line on the *lateral and/or posterior* aspect of the upper arm in and around the triceps muscles

24

Why dont we see prolapses,
extrusions or sequestration of nuclear
material in the cervical spine?

We don’t see prolapses, extrusions or sequestration of nuclear material because of the presence of the UV joints and development of the ‘bivalve disc’

25

How is the horizontal fissuring of the annulus in the cervical spine?

- Begins towards end of first decade of life
- Is universal in adult cervical discs
- Often almost completely divides posterior
2/3 of disc in later life

26

What happens in the cervical spine by 25?

By age 25, fissuring spreads throughout IVD,
and the nucleus (upper 4) disappears

27

The fissuring frequently extends right through the IVD between the 2 UV joints, leaving only the ___ relatively intact

The fissuring frequently extends right through the IVD between the 2 UV joints, leaving only the *anterior annulus* relatively intact

28

Such extensive fissuring changes the IVD, in middle life, from a structure which deforms around a central nucleus on movement (like L Spine), to a ____ with a ‘gliding joint’ between its upper and lower parts,
which allows translation of several mm forwards and backwards in full F and E

Such extensive fissuring changes the IVD, in middle life, from a structure which deforms around a central nucleus on movement (like L Spine), to a *bipartite disc* with a ‘gliding joint’ between its upper and lower parts,
which allows translation of several mm forwards and backwards in full F and E

29

What is the suboccipital region?

The joint between the occiput and the atlas

30

What joints form the craniovertebral joints?

- Atlanto-occipital (0-C1)
- Atlanto-axial (C1 – C2)
