Quick Facts
Origin: Posterior divisions of the anterior rami of fifth lumbar to second sacral nerves (L5—S2).
Course: Emerges from the sacral plexus to pass through greater sciatic foramen inferior to the piriformis. It enters the gluteal region to provide motor innervation to gluteus maximus.
Branches: None.
Supply: Motor innovation to gluteus maximus.

Origin
The inferior gluteal nerve is formed by the posterior divisions of the anterior rami of fifth lumbar to second sacral nerves.
Course
The inferior gluteal nerve leaves the pelvic cavity through the greater sciatic foramen, inferior to piriformis muscle, and enters the gluteal region to supply gluteus maximus, the largest muscle in the gluteal region. Throughout its course, the inferior gluteal nerve is accompanied by the inferior gluteal artery and vein.
Branches
There are no named branches.
Supplied Structures
