26
Anterior pelvic rotation
accomplished by hip flexors
27
Posterior pelvic rotation
accomplished by hip extensors
28
What can excessive rotation of the pelvis change?
The curvature of the spine
29
Excessive anterior and posterior rotation directly impacts...?
The lumbar spine
30
Abnormal hip rotation means what?
Really tight hip flexors and hip extensors
31
Sternocleidomatoid
O: Anterior clavicle and manubrium I: mastoid process A: flexion, rotation, lateral flexion
32
Erector Spinae
O/I: Occipital bone, cervical spine, thoracic spine, lumbar spine, pelvis A: Extension
33
Quadratus Lumborum
O: Posterior Iliac crest I: rib 12 and transverse processes of L1-L4 A: extension, rotation
34
Rectus Abdominis
O: crest of pubis I: ribs 5-7 and xyphoid process A: Flexion, rotation
35
External Oblique

38
How many individual articulating vertebrae are there?
24; 7 cervical, 12 thoracic, 5 lumbar
39
What motion occurs between the vertebrae?
Gliding (vertebrae are arthrodial joints)
40
What are the 3 normal curves?
Cervical and Lumbar spine = lordotic curve Thoracic spine = kyphotic curve
41
What is an abnormal curve known as?
Lateral curve = scoliosis
42
What are the special names for the first to cervical vertebrae?
C1 = atlas C2 = axis
43
What happens to the architecture between vertebrae C2-L5?
They get bigger, thicker, and stronger as you go down the spine
44
There's minimal movement between which vertebrae?
C2- L5
45
How many pairs of ribs are there?
12 pairs
46
How many true ribs are there?
7 pairs of true ribs attach directly to the sternum
47
How many false ribs are there?
5 pairs of false ribs (3 pairs attach indirectly to sternum and 2 pair of floating ribs- end are free)
48
Where is the Atlantooccipital Joint?
At the occipital condyles sitting on top of C1 vertebrae
49
What kind of motion occurs in the Atlantooccipital Joint?
Motion of the skull rocking back and forth on C1
50
What allowed motion occurs in the Atlantooccipital Joint?
Capital flexion and extension
51

Between C1 and C2
52
What kind of joint is the Atlantoaxial Joint?
Trochoid Joint
53
The Atlantoaxial Joint is the most..?
Most mobile of any 2 vertebrae and most cervical rotation occurs here
54
What type of motion occurs at the Intervertebral disks?
Gliding motion; arthrodial joint
55
What are the 2 parts of the Intervertebral disk?
1. Nucleus pulposus 2. Annulus fibrosus
56
Nucleus Pulposus
held in place by cartilage on both sides
57
Annulus Fibrosus
Fibrocartilage that holds the Nucleus Pulposus in place
