A. sartorius muscle B. gluteus medius muscle C. biceps femoris muscle D. semimembranosus muscle is best stretched by moving the hip into extreme adduction in front of the 15. Agonist muscles during hip extension include all of the following except the: A. sartorius muscle. B. biceps femoris muscle. C. semitendinosus muscle. D. semimembranosus muscle.

Answer 1

Answer 1: (C) Anteriorly and flexion. ( The two muscles that make up the iliopsoas group are the psoas major and iliacus)

Answer 2: (B) Acetabulum. ( The rectus femoris muscle has two origins at the anterior inferior iliac spine of the pelvis and the upper margin of the acetabulum.)

Answer 3: (C) Anteriorly and flexion. (The muscle does adduct and medially rotate the thigh but its primary function is hip flexion)

Answer 4: (A) The adductor magnus muscles.

Answer 5: (C) Rectus femoris muscles.

Answer 6: (B) It is innervated by obturator nerve. (The long head of the biceps femoris is a weaker knee flexor when the hip is extended).
