Obturator Externus - Everything You Need To Know - Dr. Nabil Ebraheim

Dr. Ebraheim’s educational animated video describes the anatomy of the obturator externus muscle. The obturator externus is one of the six short external rotators of the hip. Origin: it arises from the obturator foramen and the obturator membrane. Insertion: it inserts into the trochanteric fossa of the femur. Action: it laterally rotates and adducts the thigh. Innervation: the obturator externus muscle is innervated by the posterior division of the obturator nerve. Six short external rotators of the hip: 1-Piriformis muscle. 2-Superior gemellus muscle. 3-Obturator internus muscle. 4-Inferior gemellus muscle. 5-Obturator externus muscle. 6-Quadratus femoris muscle. The short external rotators are used to protect the sciatic nerve. The sciatic nerve will be behind these muscles. Follow me on twitter: https://twitter.com/#!/DrEbraheim_UTMC
