Question

Quizplus · Accepted Answer

The obturator externus muscle plays a role in lateral rotation of the thigh at the hip joint, as it originates from the external surface of the obturator membrane and surrounding bone and inserts into the trochanteric fossa of the femur. It does not contribute to medial rotation, flexion of the thigh, or extension of the trunk.
