Q1. What is the correct sequence of foramina traversed by the pudendal nerve?
- Inguinal canal, then lesser sciatic foramen
- Obturator canal, then greater sciatic foramen
- Lesser sciatic foramen, then greater sciatic foramen
- Greater sciatic foramen, then lesser sciatic foramen
Q2. Which ligament lies immediately adjacent to the pudendal nerve as it crosses near the ischial spine?
- Sacrospinous ligament
- Inguinal ligament
- Anterior longitudinal ligament
- Iliolumbar ligament
Q3. The pudendal canal is formed by fascia associated with which muscle?
- Piriformis
- Gluteus maximus
- Iliacus
- Obturator internus
Q4. Which three branches are classically considered the major branches of the pudendal nerve?
- Ilioinguinal, genitofemoral, and obturator
- Inferior rectal, perineal, and dorsal nerve of the penis or clitoris
- Superior rectal, obturator, and femoral
- Sciatic, tibial, and common fibular
Q5. Which pudendal branch provides motor supply to the external anal sphincter?
- Posterior femoral cutaneous nerve
- Dorsal nerve of the penis
- Obturator nerve
- Inferior rectal nerve
Q6. Which pudendal branch gives rise to posterior scrotal or posterior labial nerves?
- Superior gluteal nerve
- Inferior rectal nerve
- Perineal nerve
- Pelvic splanchnic nerve
Q7. Which perineal muscle is supplied by motor branches associated with the pudendal nerve?
- Bulbospongiosus
- Internal anal sphincter
- Detrusor
- Piriformis
Q8. Which perineal muscle that stabilizes the crus of the penis or clitoris receives pudendal motor innervation?
- Obturator internus
- Detrusor
- Piriformis
- Ischiocavernosus
Q9. Why is the ischial spine an important landmark for a pudendal nerve block?
- The nerve passes close to the ischial spine
- The nerve passes through an ischial foramen within the spine
- The nerve originates within the ischial spine
- The nerve terminates inside the ischial spine
Q10. Which vessels commonly accompany the pudendal nerve through much of its perineal course?
- Femoral vessels
- Inferior mesenteric vessels
- External iliac vessels
- Internal pudendal vessels
