Q

Sally has a pain on the right side of her neck, if she tilts her head towards the right side she feels pain? What is causing this and why?

A

Most likely joint pain rather than muscle as she is closing the joints

Q

Middle scalene origin

A

Origin: the posterior tubercles of the transverse process of the lower six cervical vertebrae

25
Middle scalene insertion
Insertion: attaches to the 1st rib
26
Action of middle scalene
Elevates 1st rib or laterally flexes to the same side
27
Posterior scalene origin
Origin: by 2 or 3 separate tendons, from the posterior tubercles of the transverse process of the lower 2 or 3 cervical vertebrae
28
Posterior scalene insertion
Outer surface of the 2nd rib, behind the attachment of the anterior scalene
29
Posterior scalene action
Elevates 2nd rib & laterally flexes to the same side
30
Deep neck flexors - DNF
31
Longus Colli origin
Transverse process of C5 - T3
32
Longus colli insertion
Anterior arch of the atlas (C1)
33
Longus colli action
Ipsilateral & rotation side: assists in lateral flexion to the same side Acting bilateral: Flexes the head and neck
34
Longus capitus origin
Come from the transverse processes of the 3rd, 4th, 5th and 6th cervical vertebrae
35
Longus capitus insertion
Into the occipital bone (skull)
36
Posterior Cervical Muscles
37
Posterior cervical muscles
Neck extensors that balance out the forces that are applied by our deep neck flexors
38
Rectus Capitus Posterior Major Origin
Spinous process of axis (C2)
39
Rectus capitus posterior major insertion
Occipital bone
40
Rectus Capitus Posterior Major Action
Bilateral (extend) Unilateral (rotates)
41
Rectus capitus posterior minor origin
Spinous process of C2
42
Rectus capitus posterior minor insertion
Occipital bone
43
Rectus capitus posterior minor origin
Same as major
44
Thoracic vertebrae
45
Disc degeneration
46
What does the vertebral column consist of?
- 24 vertebrae - Sacrum - Coccyx - The spinal cord through the foremen magnum
47
What is the spinal cord protected by?
Meninges
48
What do ligaments of the spine help do?
1) Reinforce the vertebral column 2) Stabilize intervertebral joints
49
What is the vertebral canal?
A hollow space inside the vertebrae which encloses the spinal cord
50
Cervical spine landmarks
- superior articular processes and facets - inferior articular - bifid spinous process - transverse process & foramina
51
Thoracic Spine Landmarks
- spinous process - transverse process - transverse costal facet - superior costal facets - body - inferior notch - inferior costal facets - vertebral foramen - superior articular processes and facets
52
Lumbar spine landmarks
- Vertebral foramen - Spinous process - Transverse process - Body - Superior articular processes and facets - Inferior articular processes and facets - Inferior notch
53
Sacrum landmarks
- superior articular processes - sacral alae - body - median crest - promontory - sacral canal - first dorsal (posterior) sacral foramina - first pelvic (anterior) sacral foramina - inferior lateral angles
54
What does the Sternum consist of?
- Manubrium - Body of the sternum - Xiphoid process
55
How many ribs do humans have?
12 in total - 7 true ribs (connect directly to the sternum) - 5 false ribs (don’t articulate directly with the sternum) Rib 11 & 12 are called floating ribs as they have no anterior attachment
56
What are the anterior ends of all ribs made from?
Costal cartilage
57
Name the 3 muscles of the spinal flexors
1) Longus capitus 2) Longus colli 3) Quadratus lumborum
58
Longissimus muscles classified in:
Capitis Cervicis Thoracis Extend & laterally flex the vertebral column
