28
Which of the following stages of vertebral dislocation can cause spinal cord injury? a. stage 1 b. stage 2 c. stage 3 d. stage 4
d. stage 4 (AKA spondylolisthesis) the spinal cord isn't usually injured (because of the large vertebral canal) unless its a severe injury

a. anterior longitudinal ligament
35
What's the most common cervical vertebrae injury?
vertebral arch of axis injury
36
Which vertebra has the smallest foramen due to the pedicle joining with the vertebral body?
L5
37
osteophytes growing at vertebral facet joints are called a. spondylosis b. osteoarthrosis
b. osteoarthrosis
38
osteophytes growing at the margins of the vertebral bodies are called a. spondylosis b. osteoarthrosis
a. spondylosis
39
Why do most herniations of the IVD occur posterolaterally instead of just posteriorly?
because of the PLL (posterior longitudinal ligament)
40
What innervated the facet joints?
innervated by medial branches of the posterior ramus of two adjacent spinal nerves
41
What extends from lamina to lamina? a. nuchal ligament b. ligamenta flava c. inter-transverse ligament d. supraspinatus ligament e. inter-spinous ligament
b. ligamenta flava

44
Which of the following limits the "no" movement? a. Alar Ligament b. Superior Long band c. Inferior Long band d. Transverse ligament
a. Alar Ligament
45
Which of the following are due to a variation in the length of the intervertebral discs? a. primary curvatures of spine b. secondary curvatures of spine c. scoliosis
b. secondary curvatures of spine

b. thoracic
50
Which nerves are usually compressed in sciatica?
S5/L1
51
Why does sciatica often occur in the lumbar region?
the intervertebral foramina are smaller, and the diameter of the spinal nerve is larger

b. equatorial branches
56
Which of the following supply the connective tissue surrounding the vertebra? a. periosteal branches b. equatorial branches c. spinal branches d. nutrient branches

recurrent meningeal branches (of Luschka)
62
Most of the vertebral column is innervated by \_\_X\_\_, except the facet joints are innervated by the \_\_\_Y\_\_\_
X= recurrent branches of Luschka Y= medial branch of the posterior rami of two adjacent spinal nerves
63
