A

Anteriorly

24
Q

In which section of the spine contain the joints of Luschka?

25
Q

When is the annulus stressed in the C/S?

A

Extension - different than the lumbar spine where annulus is stressed with flexion and rotation

26
Q

Damage to what ligament is usually associated with disc herniations in the C/S?

27
Q

What is the orientation of the facet joints in the lower cervical region?

A

45* from the horizontal plane

28
Q

What occurs during extension in the lower C/S?

A

Inferior glide of the facet with posterior tilt and posterior translation

29
Q

What are the functions of the C/S?

A

Motion and protects the spinal cord

30
Q

What is the shape of the atlanto-occipital joint and what motion does it do?

A

Convex on concave - “yes”

31
Q

What occurs during flexion of the OA joint?

A

Occipital rolls forward and glides posteriorly

32
Q

What is ROM for the OA joint?

33
Q

What does the atlantoaxial (AA) joint do?

A

Rotation - “no”

34
Q

What is ROM for the AA joint?

A

45* to both sides - 55-58% of total motion

35
Q

What occurs during flexion?

A

Anterior tilt and anterior glide

36
Q

What occurs during extension?

A

Posterior tilt and posterior translation

37
Q

What occurs during rotation?

A

Coupled with ipsilateral lateral flexion

38
Q

What occurs during lateral flexion?

A

Coupled with ipsilateral rotation

39
Q

What occur to the same side in the C/S?

A

Side bending and rotation

40
Q

What limits extension?

A

Facet joints and discs

41
Q

What limits flexion?

A

Posterior ligaments between the spinous processes

42
Q

What is the action of the trapezius?

A

Extension, ipsilateral lateral flexion, and contralateral rotation

43
Q

What is the function of the levator scapulae?

A

Ipsilateral flexion and rotation, produces posterior sheer, and increases activity with forward head

44
Q

What muscle pulls the vertebrae posteriorly?

A

Levator scapulae

45
Q

What muscles provide compression to stabilize the C/S?

A

Anterior muscles

46
Q

What is the function of the scalenes?

A

Frontal plane stabilizers, assist with breathing, flexion, ipsilateral flexion, and contralateral rotation

47
Q

What two muscles work together?

A

Levator scapulae and scalenes

48
Q

What is the function of the longissimus capitis and cervicis?

A

Compression, stabilize head, and frontal plane stabilizers

49
Q

What are two important muscles to strengthen in order to stabilize our head?

A

Longissimus capitis and cervicis

50
Q

What is the function of the suboccipital muscles?

A

Occipital extension, ipsilateral rotation, lateral flexion, proprioceptive, and fine tune motion

51
Q

What is the function of the splenius capitis and cervicis?

A

Extension and ipsilateral rotation

52
Q

What muscles are the prime movers?

A

Splenius capitis and cervicis

54
Q

What muscles are a common source of headaches?

A

Splenius capitis and cervicis

55
Q

What is the function of the SCM?

A

Ipsilateral lateral flexion and contralateral rotation

56
Q

What is the function of the longus capitis and colli?

A

Compression of the C/S and stabilizers that work with the upper trapezius

59
Q

What is another name for the posterior longitudinal ligament?

A

Tectorial ligament
