sciatic nerve
Lower body cable
The sciatic nerve is the largest nerve in the human body, running from the lower spine down through the buttock and along the back of each leg.
When irritated or compressed, it causes sciatica—pain radiating down the leg: The herniated disc was pressing on her sciatic nerve.
