The superior gluteal nerve is a nerve that originates in the pelvis which supplies the gluteus medius, the gluteus minimus, and the tensor fasciae latae muscles.

[edit] Structure

The superior gluteal nerve originates in the sacral plexus. It arises from the dorsal divisions of the fourth and fifth lumbar and first sacral nerves: it leaves the pelvis through the greater sciatic foramen above the piriformis, accompanied by the superior gluteal artery and the superior gluteal vein. It then divides into a superior and an inferior branch.

The superior gluteal nerve and vessels travel above the piriformis muscle through the greater sciatic foramen; the inferior gluteal nerve and vessels travel below the muscle.

Lumbosacral plexus

lumbar plexus: iliohypogastric - ilioinguinal - genitofemoral (femoral branch/lumboinguinal, genital branch) - lateral cutaneous of thigh (patellar) - obturator (accessory obturator) - femoral (saphenous)

sacral/coccygeal plexus: to quadratus femoris - to obturator internus - to the piriformis - superior gluteal - inferior gluteal - posterior cutaneous of thigh
sciatic: tibial (sural - medial plantar - lateral plantar) - common fibular (deep fibular - superficial fibular)

pudendal plexus: perforating cutaneous - pudendal (dorsal of the penis/clitoris, inferior anal, perineal and posterior scrotal/labial) - anococcygeal
