Q

What nerves can cause tension headache (which begins posteriorly and radiates toward the vertex)? Where are they located?

A

Greater occipital nerves- distinctly palpable if inflamed

1’’ infero-laterally of the INION (external occipital protuberance)

17
Q

Fracture within pars interarticularis

slippage of vertebrae respective to each other resulting from above fracture is:

A

Spondylolysis

spondylolysthesis

18
Q

A

Located between ASIS and Highest point of iliac crest- corresponds to the L5 vertebral level

19
Q

What vertebral level is the horizontal portion of vertebral arteries?

A

C1 of ATLAS

20
Q

What vertebral level do arteries enter transverse foramen?

A

C6

21
Q

7 Atypical characteristics of C1 ATLAS

A
  1. NO body
  2. NO spinous process
  3. Has Lateral Masses
  4. Superior articular facets articulate with occipital condyles of skull
  5. Anterior arch (articulates with dens of C2)
  6. Posterior arch (groove on superior border for vertebral artery)
  7. Transverse foramina
22
Q

5 Atypical characteristics of C2 AXIS

A
  1. Body
  2. Dens (odontoid process)
  3. Transverse foramen
  4. Spinous process
  5. Pars interarticularis (site of hangmans fracture)
23
Q

Fact about vertebra prominens

A

in 30% of population its at C6

24
Q

Processes and joints specific to cervical vertebrae

A 
Uncinate process
Uncovertebral joints (of Lushka)
25
Q

How do you identify a lumbar fracture of the pars interarticularis?

A

Oblique radiograph shows a “scotty dog”

if the scotty dog has a “COLLAR” = fracture

26
Q

Articular process orientations of Cervical vertebrae? Thoracic vertebrae? of Lumbar vertebrae

A
  1. Cervical- superior-inferior about 10degrees
  2. thoracic- anteriorly-posteriorly
  3. Lumbar- medially-laterally
27
Q

A

Cornua

28
Q

what is the hole at the bottom of the sacrum? What are the holes lined up along the anterior and posterior surface of the sacrum? What is tunnel going down into the sacrum? What is articular surface of sacrum?

A

sacral hiatus and cornua (horns)
Anterior and posterior sacral foramina
sacral canal
sacroiliac joints

29
Q

What is the fibrocartilage portion of intervertebral disc? What is gel portion called?

A 
Annulus Fibrosus (fails and permits herniation)
Nucleus Palposus (part that actually herniates)
30
Q

What ligament is punctured for spinal tap and epidural injection?

A

Ligamentum flavum

31
Q

What is the floor of the suboccipital triangle; continuous with ligamentum flavum?

A

Transverse ligament of the atlas

33
Q

what ligament is continuous with the supraspinous ligament and is located in the cervical region only?

A

Ligamentum nuchae
