The superior gluteal nerve arises from the posterior roots of L4, L5, and S1 in the lumbosacral plexus

The superior gluteal nerve arises from the posterior roots of L4, L5, and S1 in the lumbosacral plexus. It exits the pelvis through the superior part of the greater sciatic notch, just superior to the piriformis tendon. It courses between the gluteus medius and minimus, supplying both muscles, as well as the tensor fascia lata. The inferior gluteal nerve arises from the posterior roots of L5, S1, and S2 in the lumbosacral plexus and exits the pelvis through the greater sciatic notch, under the piriformis. It courses on the deep surface of gluteus maximus and provides the sole motor innervation for this muscle.
