1

In the upper cervical spine the A-O joint is con___ on con___

convex on concave

2

In the upper cervical spine the A-A joint is at a

20* orientation to the horizontal plane

3

The mid-lower cervical plane is made up of C_-C_.
C7 is a ___________ segment.
The orientation is ___ to the horizontal and frontal planes.

C3-C7
transitional
45*

4

Name 2 interbody joints

C2/3
L5/S1

5

Interbody joints are considered ________ joints.

synarthrodial

6

Name two characteristics of interbody synarthdrodial joints.

1) cartilaginous
2) permit slight to no amount of movement

7

Each interbody joint contains what 3 components?

1) intervertebral disc
2) vertebral endplates
3) adjacent vertebral bodies

8

What is the function of the interbody joint?

optimized the function of the spine.

9

What is the nucleus pulposus?

inner component pulp-like gel shock absorption distribution of forces

10

What is the annulus fibrosus?

Concentric rings of fibrocartilage tissue (helps w/ distribution of forces)

11

What is the vertebral endplate?

Cartilaginous caps made of connective tissue cover the superior and inferior surfaces of the vertebral bodies.

12

True or false: the facet surfaces of C2 and C7; allow for motion in only 2 planes?

False: The facet surfaces of C2-C7 allow for motion in all 3 planes.

13

The facet surfaces of C2-C7; are oriented at a ___ angle between the horizontal and frontal planes.

45*

14

The facet surfaces of C2-C7 can be compared to what common-place structure?

shingles on a roof

15

Along with the facet joints, what other structures guide vertebral motion?

Muscles, ligaments, gravity and deterioration of the TPs and SPs.

16

What position at the AO joint creates a posterior glide occipital condyles?

flexion

17

What position would you place the AO joint in to create a maximal anterior glide of the left occipital condyle?

Extension w/ left lat. flexion & coupled right rotation

18

What 2 positions could you place the AO joint in to test maximal posterior glide of the left occipital condyle?

1) flexion w/ right lat flexion & coupled left rotation
2) flexion w/ left rotation & right lat flex.

19

What 2 positions could you place the AO joint in to test maximal anterior glide of the right occipital condyle?

1) extension w/ right lat flexion & coupled left rotation
2) extension w/ left rotation & coupled right lat flex.

20

What are 5 deep posterior muscles supporting the cervical spine?

1) multifidus
2) semispinalis cerivicis
3) semispinalis capitis
4) splenius capitis
5) upper trapezius

21

What are 4 deep anterior muscles supporting the cervical spine?

1) longus capitis
2) longus colli
3) scalenes
4) sternocleidomastoid

22

The cervical deep muscles are local __________________?

stabilizers of the spine

23

The cervical deep muscles attach __________________?

directly to the vertebrae

24

The cervical deep muscles control ___________ and ________________.

intersegmental motion (stiffens) AND the position of the vertebrae

25

What is the purpose of the cranial cervical flexor test?

assess strength of the deep cervical muscluarture

26

What is the equipment used for cranial cervical flexor test?

stabilizer unit

27

What is the procedure of the cranial cervical flexor test?

ask pt to not head on neck.
Avoid retraction and isolate movement to upper cervical spine.
Avoid activation of SCM

28
