When walking, the action of the iliopsoas muscle results in what motion at the hip joint?

• Abduction

• Adduction

• Extension

• Flexion

• Medial rotation

Sartorius muscle is innervated by:

• Obturator nerve

• Femoral nerve

• Nerve to vastus medialis

• Superior gluteal nerve

• Lateral cutaneous nerve of the thigh

All the following statements about sartorius muscle are correct EXCEPT:

• It flexes the leg at the knee joint.

• It flexes the thigh at the hip joint

• It laterally rotates the thigh at the hip joint.

• It adducts the thigh at the hip joint

• It is attached to the anterior superior iliac spine

• Rectus femoris

• Vastus intermedius

• None of the above

Concerning the quadriceps femoris, all are true EXCEPT:

• Arises entirely from the femur

• Innervated by the femoral nerve

• The vastus medialis arises from the linea aspera

• It prevents lateral displacement of patella
