Superior gluteal nerve
The superior gluteal nerve (latin: nervus gluteus superior) is a motor nerve that originates from the sacral plexus and innervates muscles in the gluteal region.
The superior gluteal nerve arises from the ventral rami of the fourth and fifth lumbar nerve (L4 - L5) and the first sacral nerve (S1).
The superior gluteal nerve runs through the suprapiriform foramen, then it goes between the gluteus medius and gluteus minimus. Along its course the superior gluteal nerve accompanies the superior gluteal artery.
The muscles innervated by the superior gluteal nerve are the gluteus medius, gluteus minimus, and tensor fasciae latae.
