True

8

The uncovertebral joints extend from where to where?

C3-T1

9

T or F

Uncovertebral joints are diarthrodial articulations

True

10

What did Clausen et al. research on the cervical spine joints and their associated motions find the main function of the uncinate processes to be?

Effective at reducing motion coupling and primary cervical motion

11

Where is the most common area for pathology in C-Spine

C5/C6

12

Functionally the cervicothoracic junction includes what structures?

C7 vertbera
T1 & T2
Ribs 1 and 2
Manubrium

13

T or F

The Cervicothoracic junction forms the Thoracic Outlet

True

14

Is the PLL or ALL more susceptible to injury and pain

PLL

15

T or F

Proprioception of the Trapezius comes fro C2-C3

False

C3-C4

16

T or F
The Anterior Scalene insertion is the second rib

False

1st

17

What scalene attaches to the 2nd rib

Posterior

18

T or F

Posterior Scalene innervation is from C3-C8

False

C6-C8

19

T or F

The superior portion of trapezius is often stretched in hyper-extension injury of the cervical spine

False

Hyper-flexion

20

What ligament is involved in hyperextension of the neck during an CAD injury

ALL

21

What is the largest muscle in the anterior neck. What are its proximal and distal attachments

SCM
Mastoid
Posterior aspect of the medial 1/3 of clavicle and the manubrium

22

T or F
Proprioception of the SCM is provided by C2 C3 dorsal primary rami

False

VPR

23

Wry Neck aka ?

Torticollis

24

T or F

Torticollis is often associated with injury to the Scalenes on one side at the time of birth during a difficult delivery

False

SCM not scalenes

25

Describe the head position in Torticollis

SCM muscle contraction causes rotation of the head to the opposite side and flexion of the neck to the same side.

26

What is the function of the Levator Scapulae with the scapula stabilized?

Produces rotation and side bending of the neck to the same side; while acting bilaterally cervical extension is produced

27

Where is the origin of the Levator Scapulae?

TP's of C1-C4

28

The Rhomboid minor arises from where?

The spinous processes of C7 & T1

29

The Rhomboid Major arises from where?

SP's of T1-T5

Clay Shoveler's Fracture is a type of hyperextension avulsion injury

False

Hyperflexion

31

Symptoms of TOS include:

Tingling or numbness in the fingers, hands, arm, shoulder or neck
Weakness of the hand or arm
Aching in the shoulder or neck
Worsened when the arm is lifted above shoulder height

32
