Answer to Question 1

ANS: D
The most common disks affected by herniation are the lumbosacral disksthat is, L5-S1 and L4-L5.

Answer to Question 2

ANS: C
Spondylolisthesis occurs when there are vertebra slides forward or slips in relation to below it. Degenerative disk disease is a pathophysiological cause of spondylolisthesis but is not the defini-tion of the displacement. Spondylolysis is a structural defect of the spine.
Spinal stenosis is a narrowing of the spinal canal.
