Q

What is the structure of the typical cervical vertebrae (C3-C6)?

A
  • Body is small
  • Transverse foramen on transverse process

Q

What is the role of the transverse ligament? What motion does it help limit?

Q

What is the role of the alar ligament? What motion does it help limit?

A
  • Taut in neck flexion and with axial rotation

- Limit lateral flexion and prevent distraction of C1 on C2

Q

What occurs in the cervical spine with protraction? Retraction?

A
  • Protraction
    1. Upper cervical extension
    2. Lower cervical flexion
  • Retraction
    1. Upper cervical flexion
    2. Lower cervical extension

Q

What occurs at the atlanto-occipital joint arthrokineamtically?

A

Moving convex on concave:
Flex - ant roll and post glide
Ext - post roll and ant glide
Lateral flex - opposite roll and glide

16
Q

What occurs at the atlanto-axial joint arthrokineamtically flex/ext?

A
  • Tilt forward/backwards of atlas on axis

- No glide because anterior arch stops posterior glide and dens stops anterior glide

17
Q

What occurs at the atlanto-axial joint arthrokineamtically rotate?

A
  • Anterior arch and dens = rotate

- Inferior facet of atlas will glide posterior ipsilateral and anterior contralateral

18
Q

What lig limits rotation at the AA joint?

A

Alar lig

19
Q

What lig limits flex at the AA joint?

A

Transverse lig

20
Q

What coupling motions occur with lateral flexion and rotation at the cervical spine?

A

-Coupled in same direction otherwise facet joints would come in contact with one another

21
Q

What occurs at the facet joints of C3-C7 arthrokinematically with flex/ext?

A

Flex - inferior facet glides anter and superior

Ext - inferior facet glides posterior and inferior

22
Q

What occurs at the facet joints of C3-C7 arthrokinematically with rotation?

A

Ipsilateral - Inferior facet glides posterior and slightly inferior
Contralateral - inferior facet glides anterior and slightly superior

23
Q

What occurs at the facet joints of C3-C7 arthrokinematically with lateral flexion?

A

Ipsilateral - inferior facet glides inferiorly and slightly posterior
Contralateral - inferior facet glides superior and slightly anterior

24
Q

What is the overall function of the cervical spine?

A
  1. Stability and protection (spinal cord/vert arteries)
  2. Most flexibility
  3. Free space to prevent impingement
25
Q

What are the concerns with muscular imbalances and poor posture?

A
  1. Excessive tension on levator scapular and semispinalis capitus with prolonged protraction
  2. Rectus capitis posterior major likely to become fatigues as it is acting to produce prolonged extension to level the head/eyes
