18
Q

Zygopohyseal JOint (C1-S1)

A

Planar synovial

19
Q

Anterior longitudinal ligament

A

Travels on the anterior surface of the vertebral body

20
Q

Joint of Luschka

A

In Cervical joints, the joint between the unilateral process of the inferior vertebra and beveled inferior surface of the superior vertebra

UNCOVERTEBRAL

21
Q

Whiplash results in what?

A

Excessive stretching/tearing of the anterior longitudinal ligament

A recoil can also result in hyperflexion injury

22
Q

What to do when fracture of vertebral column occurs

A

Hyper extension of the anterior longitudinal ligament will help realign fragments of bone to prevent further injury to spinal cord.

23
Q

Posterior longitudinal ligament

A

Travels on the dorsal aspect of the vertebral bodies

24
Q

Ligamentum Flavum

A

Pale yellow fibers that travel on the ventral surface of the vertebral lamina

25
Q

Interspinous ligament

A

Travel between adjacent spinous processes

26
Q

Intertransverse ligament

A

Not well defined in cervical region

Fibrous cord in the thoracic region, thin membranes in the lumbar region

27
Q

Supraspinous ligament

A

Travels on dorsal surface of the spinous process

Continues as the ligamentum nuchae in the cervical region

28
Q

Intervertebral discs have two parts

A

Annulus fibrosis: tough fibrous outer region

Nucleus pulposus: soft gelatinous inner portion

29
Q

Herniation of the nucleus pulposus typically occurs where?

A

Poserolaterally

At L4/5 an L5/S1 (where discs are larger and more mobile.)

30

    • posterior atlantooccipictal membrane (from anterior surface of the posterior arch of the atlas to the posterior internal margin of the foremen magnum of occipital bone)
31
Q

    -Transverse L. Of atlas (around odontoid process, from tubercle of transverse L to contralateral tubercle of transverse L.)
    -inferior longitudinal band (from C2 to transverse L)
    B. Alar L (from odontoid process of axis to the lateral margins of the foramen magnum of occipital bone.
    C. Apical L of dens (apex of dens to anterior internal margins of foramen magnum
32

    B. Posterior longitudinal L. (Travels on the dorsal surface of the vertebral body onto anterior wall of sacral canal
    C. Ligamentum flavum (travel on ventral surface of vertebral laminae onto posterior wall of sacral canal
    D. Illiolumbar (travels from L5 transverse process to iliac crest
    - lumbosacral L. (Travel from L5 trans process and body to sacral ala)
