Sample Data
| Content | At the hip joint 1: the obturator internus produces lateral rotation {{c1::True}}2: the gluteus medius produces abduction {{c2::True}}3: the gluteus minimus produces medial rotation {{c3::True}}4: the obturator externus produces medial rotation {{c4::False}} |
| Note | 1.True; 2.True; 3.True; 4.FalseLateral rotation is by any muscle passing obliquely or transversely across the back of the hip joint and behind the vertical axis around which the femoral head rotates. Gluteus maximus is the most powerful and the others are more active as stabilisers of the hip joint but obturator internus together with the gluteus medius, piriformis, gemelli and quadratus femoris are lateral rotators (A true).
 Medial rotators are any muscle whose line of pull passes across the front of the hip joint. The anterior portions of both gluteus minimus (C true) and gluteus medius can thus act as medial rotators as do the psoas major and illiacus. The obturator externus passes behind the hip joint, and although mainly a stabiliser of the hip joint, is therefore also a lateral rotator of the extended thigh (D false). Abduction is produced by the gluteus medius and gluteus minimus assited by piriformus(B true).

| Front | Stratified squamous epithelium lines the 1: oesophagus 2: vocal cords 3: vagina 4: membranous urethra |
| Back | 1.True; 2.True; 3.True; 4.FalseThe membranous urethra (males only i.e. just before the penile urethra) is transitional epithelium. Only near the orifice is it stratified squamous. |

| Content | The superior vena cava 1: has the right phrenic nerve on its lateral side {{c1::True}}2: receives the azygos vein {{c2::True}}3: lies anterior to the right pulmonary artery {{c3::True}}4: lies to the left of the transverse sinus of the pericardium {{c4::False}} |
| Note | Lies to the right of the transverse sinus
