Intermediate Sacrotuberous Ligament Quiz

Q1. Which muscle has fibers that can blend with the sacrotuberous ligament?

• Pectineus
• Sartorius
• Gluteus maximus
• Rectus femoris

Q2. Which hamstring muscle has a relationship with the sacrotuberous ligament near the ischial tuberosity?

• Vastus medialis
• Iliacus
• Long head of biceps femoris
• Tensor fasciae latae

Q3. How does the sacrotuberous ligament contribute to the greater sciatic foramen?

• It completely closes the foramen
• It forms the obturator canal
• It forms the acetabular roof
• It helps convert the greater sciatic notch into a foramen

Q4. How does the sacrotuberous ligament contribute to the lesser sciatic foramen?

• It forms its entire anterior wall
• It closes the opening completely
• It contributes to its posterior boundary
• It has no relationship to the foramen

Q5. Which structures work with the sacrotuberous ligament to resist excessive sacral nutation?

• Sacrospinous ligament
• Transverse acetabular ligament
• Inguinal ligament
• Sacrotuberous ligament of the opposite side only

Q6. What happens to the sacrotuberous ligament during sacral nutation?

• It becomes more tense
• It becomes a synovial structure
• It disappears temporarily
• It detaches from the ischial tuberosity

Q7. Why is the sacrotuberous ligament important to sacroiliac joint mechanics?

• It separates the ilium from the sacrum
• It forms the articular cartilage of the joint
• It helps limit excessive sacral movement
• It creates unrestricted sacroiliac rotation

Q8. Which description best compares the sacrotuberous and sacrospinous ligaments?

• Both terminate at the femoral head
• Both attach only to the pubic symphysis
• The sacrospinous ligament is superficial to the sacrotuberous ligament
• The sacrotuberous ligament reaches the ischial tuberosity, while the sacrospinous ligament reaches the ischial spine

Q9. Which structure passes through the lesser sciatic foramen after curving around the ischial spine?

• Femoral nerve
• Superior gluteal nerve
• Obturator nerve
• Pudendal nerve

Q10. What is the main mechanical effect of tension in the sacrotuberous ligament?

• Unrestricted movement of the coccyx
• Complete separation of the sacroiliac joints
• Increased stability of the sacrum within the pelvic ring
• Direct extension of the knee
