More damage is caused by rupture of the ligament because it allows the atlas to move anteriorly and smash the spinal cord against the dens.

Question 3

What are the defining features of thoracic vertebrae?

Answer 3

Heart or triangular shaped body
Close lamina
Long spinous processes
Vertical facets
Rib articulations

Answer 4

inferior, superior and transverse costal facets

Question 5

Which vertebrae permit and limit the different kinds of rotation?

Answer 5

Cervical: allow flexion/extension, and lateral flexion, slightly limited rotation

Thoracic: Permit rotation, limit flexion/extension, lateral flexion

Lumbar: Permit flexion/extension, lateral flexion, very limited rotation

Question 6

If an injection is made in the sacral hiatus, what space does the injection go into?

Answer 6

Epidural space

Question 7

What is spondylolysis?

Answer 7

Breakage of articulations associated with lamina

Spondylolisthesis is actual displacement of vertebrae

Question 8

What are the two ligament between spinous processes?

Answer 8
