Q

What are the 6 facts about the cervical intervertebral discs?

A
  1. no disc between C1 and C2
  2. Discs are thicker anteriorly cos of lordosis
  3. Disc degenerative change at age 15
  4. C5/6 disc most vulnerable
    Disc is reinforced by the uncovertebral joint
  5. Cervical disc loading affected by head weight and posture

Q

How are the spinal nerve organised in the cervical spine?

A
  1. Cervical spinal nerves C1-7 emerge above their corresponding vertebrae
  2. Cervical spine nerve 8 exits below to the C7 vertebrae
  3. Cervical spinal nerve C5 exits between C5 and C4
  4. Cervical spinal nerve C8 exits betwen C7 and T1

All spinal nerves ij the thoratic and lumbar regions exits below their corrosponding verteabrae

Baso occipital condyles and lateral masses

19
Q

What is the Atlanto occipital joint classed as?

A

Condyloid joint

20
Q

What movements does the Atlanto occipital joint permit?

A

Flextion
Extention
Eg nodding

21
Q

Is there a intervertebral disc in the atlanto occipital joint?

A

No there isnt

22
Q

What are the degrees of each momvent at the Atlanto occipital joint?

A

Flextion- 3.5-15
Extention- 21
Roation- 6.6-7.9
Layeral flextion- 5-6

23
Q

What is the pivot joint of Atlanto axial joint?

A

Articulation 1 median

- anterior arch of C1 and dens of C2

24
Q

What is the gliding joint of Atlanto axial joint?

A

Articulation 2 lateral

- inferior facets of lateral masses of C1 and superior facets of C2

25

32
Q

What facts do we need to know about lateral flextion at the zygapophyseal joint?

A

Lateral flextion and rotation occur as linked movements

Lateral flextion is accompanied
by ipsilateral roation

33

Where is the unconvertebral joints located?

A

Articulation between unicinate process (inferior) and uncus (superior)

35
Q

What 3 facts do we need to know about the unconvertebral joints?

A
  1. Uncinate processes develop with age abd vary in height
  2. Joint provides motion and stability
  3. Common site for osteoarthritic changes
36
Q

What 4 factors determine movement in the cervicle spine?

A
  1. IVD
  2. Articular surfaced of zygapophyseal joints
  3. Joint capsuals
  4. Surrounding musculature
37
Q

What are the 3 main ligaments in the cervicle spine?

A
  1. Anterior longitudinal ligament
  2. Supraspinous ligament
  3. Ligamentum nuchae
38
Q

What is the anterior longitudinal ligament?

A

Starts at anterior tubercle of atlas and descends

39
Q

What is the ligamentum nuchae?

A

From the posterior tubercle of atlas and descends - continues with supraspinous ligament below

40
Q

What is the tectorial membrane?

A

From body of axis to occiput. Continues with Posterior longitudinal ligament

41
Q

What is the posterior longitudinal ligament?

A

From body of axis and descends

Continuous with the tectorial membrane above

42
Q

What is the ligamentum flavum?

A

Between the laminae of adjacent vertebrae starting at C1/C3

43
Q

A

Between transverse process of each vertebrae

Insignificant and often absent in cervical region
