Anatomical terms of muscle

The inferior gemellus muscle is a muscle of the human body. The Gemelli are two small muscular fasciculi, accessories to the tendon of the Obturator internus which is received into a groove between them.

The Gemellus inferior arises from the upper part of the tuberosity of the ischium, immediately below the groove for the Obturator internus tendon. It blends with the lower part of the tendon of the Obturator internus, and is inserted with it into the medial surface of the greater trochanter. Rarely absent.

Like the obturator internus muscle, the gemellus superior and gemellus inferior help to steady the femoral head in the acetabulum. Both muscles also help to laterally rotate the extended thigh and abduct the flexed thigh at the hip
