NERVE TO QUADRATUS FEMORIS

 

ORIGIN: Lumbosacral plexus (L4,5, S1).

COURSE/DISTRIBUTION: This nerve arises from the lumbosacral plexus and descends through the greater sciatic foramen to escape into the gluteal region below the piriformis. It then runs on the ischium deep to the sciatic nerve to reach the tendon of obturator internus and the gemelli. It  supplies the quadratus femoris by entering its anterior surface, and also the gemellus inferior.

BRANCHES: Muscular branches. 

ROOT VALUE: L4,5,S1
