Question

a typical l4/l5 disc herniation may cause radiculopathy at which nerve root?
○ l3
○ l4
○ l5
○ s1

Explanation:

In spinal anatomy, a herniated disc at the L4/L5 level typically impinges on the nerve root that exits below this disc space, which is the L5 nerve root. This is because lumbar nerve roots exit the spinal canal just below their corresponding vertebral body, so the L4/L5 disc affects the L5 root.

Answer:

L5
