Answer to Question 1

ANS: D
The five lumbar vertebrae are posterior to the retroperitoneal cavity and are designed to carry the heaviest load of the entire vertebral column with the least amount of flexibility.

Answer to Question 2

ANS: D
Magnetic resonance imaging (MRI) and CT scan are used to evaluate spinal injuries. MRI and myelography outline soft tissue abnormalities, such as disc degeneration, protrusion, or rupture. MRI is replacing myelography because it is noninvasive.
