QuestionChoice
The piriformis is labelled. The piriformis muscle is one of the deep gluteal muscles and is the most superior of this group. It originates from the anterior surface of the sacrum and passes through the greater sciatic foramen to insert on the greater trochanter of the femur. The piriformis acts to laterally rotate and abduct the thigh when the hip is flexed. It also plays a role in stabilising the hip joint. Its anatomical position makes it important clinically, as the sciatic nerve passes below it, potentially leading to piriformis syndrome when the nerve becomes compressed.
