Quizplus · Accepted Answer

The sciatic nerve is the largest nerve in the body, formed from the nerve roots of L4-S3 in the lower back. It runs down the back of each leg and divides into the tibial and fibular nerves at the knee. The pudendal nerve arises from S2-S4 and serves the pelvic floor muscles and external genitalia. The superior gluteal nerve arises from L4-S1 and supplies the gluteus medius, minimus, and tensor fasciae latae muscles.
