Guillain-Barre syndrome is an inflammatory disorder of which nerves?

Explanation:
Guillain-Barré syndrome is an inflammatory process that affects the peripheral nervous system—the nerves outside the brain and spinal cord, including the nerve roots. It is typically an autoimmune attack on the myelin sheath (Schwann cells) of peripheral nerves, leading to rapidly progressive, symmetrical weakness and areflexia. The central nervous system, comprising the brain and spinal cord, is not involved in GBS, and brainstem involvement would implicate central pathways rather than peripheral nerves. Therefore, the hallmark is inflammation of the peripheral nerves, making the peripheral nerves the correct focus.
