supraspinous ligaments

Question 2

what is the purpose of the anterior layer of the thoracolumbar fascia

Answer 2

seperate deep muscles of back from posterior wall of abdominal cavity

Question 3

what are the 3 factors that determine motion in the vertebral column

Answer 3

• thickness of IVD w/ rexpect to vertebral bodies
• size and shape of verebral bodies
• position and shape of articular processes

Question 4

in regards to IVDs and size of vertebral bodies, what will allow for more motion

Answer 4

• thicker discs

- larger bodies

Question 5

what movements are allowed in atlantooccipital and atlantoaxial joints

Answer 5

• AO: flex/ext w/ some lat flex

- AA: rotation

Question 6

describe properties to allow motion and movements in the cervical region

Answer 6

• very moveable
• large discs and cruved vertebral bodies
• horizontal facing zygopophyseal joints
• mainly lat felx w/ some flex/ext

Question 7

describe properties to allow motion in the thoracic region

-primary action?

Answer 7

• thin discs
• flat vertebral bodies
• presence of ribs
• frontal facing zygopophyseal joints
• primary action = rotation

Question 8

describe properties to allow motion in the lumbar region

Answer 8

• large discs
• large curved bodies
• saggital facing zygopophyseal joints
