Q1. Which structure passes around the ischial spine in close relation to the sacrospinous ligament?
- Pudendal nerve
- Obturator nerve
- Femoral nerve
- Genitofemoral nerve
Q2. Which artery follows the pudendal nerve around the ischial spine?
- Internal pudendal artery
- Inferior mesenteric artery
- Deep femoral artery
- External iliac artery
Q3. How does the sacrospinous ligament contribute to formation of the lesser sciatic foramen?
- It forms the femoral canal
- It helps convert the lesser sciatic notch into a foramen
- It forms the superior border of the acetabulum
- It closes the obturator foramen
Q4. Which muscle is closely associated with the pelvic surface of the sacrospinous ligament?
- Coccygeus
- Rectus femoris
- Sartorius
- Rectus abdominis
Q5. Which movement of the sacrum increases tension in the sacrospinous ligament?
- Pronation
- Circumduction
- Nutation
- Supination
Q6. How do the sacrospinous and sacrotuberous ligaments work together mechanically?
- They stabilize the sacrum and resist excessive rotation
- They promote unlimited sacral rotation
- They move the hip through flexion
- They separate the pelvic bones during standing
Q7. Which foramen does the pudendal nerve use to leave the pelvic cavity?
- Intervertebral foramen
- Greater sciatic foramen
- Obturator foramen
- Lesser sciatic foramen
Q8. Through which opening does the pudendal nerve enter the perineum after crossing the ischial spine?
- Lesser sciatic foramen
- Greater sciatic foramen
- Obturator canal
- Femoral ring
Q9. Why is the ischial spine an important landmark when considering the sacrospinous ligament?
- It forms the head of the femur
- It forms the sacral promontory
- It is the lateral attachment of the ligament and a neurovascular landmark
- It contains the obturator canal
Q10. Which statement best distinguishes the sacrospinous ligament from the sacrotuberous ligament?
- The sacrospinous ligament forms the inguinal canal
- The sacrospinous ligament attaches to the femoral neck
- The sacrospinous ligament attaches to the pubic tubercle
- The sacrospinous ligament attaches to the ischial spine rather than the ischial tuberosity
