Thigh Anatomy

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

The part of the quadriceps muscle acting on both hip and knee joints is:

• Vastus medialis

• Vastus lateralis

• 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

A muscle known for tailor master:

• Iliacus

• Psoas major

• Sartorius

• Pectineus

The longest muscle of the body is:

• Sartorius

• Gluteus maximus

• Adductor longus

• Plantaris

Which of the quadricep femoris muscles performs extension as well as flexion?

• Vastus lateralis

• Vastus medialis

• Vastus intermedias

• Rectus femoris

Which of the following muscles crosses two joints?

• Vastus lateralis

• Vastus medialis

• Vastus intermedius
