Flashcards in Chapter 2 Cervical Spine Deck (39):
1

Which vertebra has no spinous process or vertebral body?

C1

2

Which vertebrae have bifid spinoud processes?

C2-6

3

What portion of the cervical vertebrae lies bt the superior and inferior facets?

Articular pillars (or lateral masses)

4

What is located posterior to the cervical transverse processes?

Articular pillars

5

What is used by DO's to evaluate cervical vertebral motion?

Articular pillars

6

What vertebrae do the vertebral arteries pass thru?

C1-6

7

What do the vertebral arteries pass thru?

Foramen transversarium

8

Where do the scalenes originate?

Posterior tubercle of the transverse processes of the cervical vertebrae

9

Where does the anterior scalene insert?

Rib 1

10

Where does the middle scalene insert?

Rib 1

11

Where does the posterior scalene insert?

Rib 2

12

What are the actions of the scalenes?

Sidebend to same side with unilateral contraction, flex with bilateral contraction (also aid in respiration)

13

Where would you find a scalene tenderpoint in a rib dysfunction?

Posterior to clavicle at base of neck

14

Where does the SCM originate?

Mastoid and lateral half of superior nuchal line

15

Where does the SCM insert?

Medial 1/3 of clavicle and sternum

16

What are the actions of the SCM?

With unilateral contraction, will sidebend ipsilaterally and rotate contralaterally; bilateral contraction flexes head

17

Shortening or restrictions within the SCM results in what?

Torticollis

18

What ligament extends from the sides of the dens to the lateral margins of the foramen magnum?

Alar ligament

19

What ligament attaches to the lateral masses of C1 to hold the dens in place?

Transverse ligament of the atlas

20

What syndromes can weaken the alar and transverse ligaments resulting in AA subluxation?

Down's and RA

21

What are uncinate processes?

Superior lateral projections originating from the posterior lateral rim of the vertebral bodies of C3-7

22

What is the joint of Luschka (unconvertebral joints)?

The articulation of the superior uncinate process and superadjacent vertebrae

23

What is the most common cause of cervical nerve root pressure?

Degeneration of the joints of Luschka plus hypertrophic arthritis of the intervertebral synovial (facet) joints

24

Where does C8 nerve root exit?

Between C7 and T1

25

What nerve roots make up the brachial plexus?

C5-T1

26

What is the primary motion of the OA?

Flexion and extension--50% of flexion/extension of cervical spine occurs at OA

27

How does sidebending occur at OA?

Opposite rotation

28

What is the primary motion of the AA?

Rotation--50% of rotation of cervical spine occurs at AA

29

What are the mvts of C2-7

Sidebending and rotation occur to the same side

30

Main motions of C2-4?

Rotation

31

Main motions of C5-7?

Sidebending

32

Lateral translation to the right will cause what motion?

Left sidebending

33

What if you feel a deep sulcus on the right at the OA joint?

Rotated right, sidebent left

34

How do you evaluate the AA?

Flex cervical spine to 45 degrees to lock out rotation of typical cervical vertebrae

35

An acute injury to the cervical spine is best treated how?

MFR or counterstrain

36

How does cervical foraminal stenosis present?

Neck pain radiating to upper extremity

37

What are the S/S of cervical foraminal stenosis?

Increased pain with neck extension, posiive Spurling's, paraspinal muscle spasm, posterior and anterior cervical tenderpoints

38

Which vertebra actually rotates, the atlas or axis?

Atlas rotates on axis

39

Which cervical segment is best assessed by flexing neck to 45 and rotating?

C1
