Intermediate Ilioinguinal Nerve Quiz

Q1. Does the ilioinguinal nerve normally enter the inguinal canal through the deep inguinal ring?

• No, because it never enters the inguinal canal
• Yes, it always enters through the deep ring
• Yes, it enters through the femoral ring
• No, it enters by piercing internal oblique

Q2. Which nerve generally runs superior to the ilioinguinal nerve across the posterior abdominal wall?

• Obturator nerve
• Iliohypogastric nerve
• Sciatic nerve
• Femoral nerve

Q3. What is the usual motor contribution of the ilioinguinal nerve?

• Gluteus maximus
• Hamstrings
• Quadriceps femoris
• Internal oblique and transversus abdominis

Q4. Which sensory territory of the thigh is supplied by the ilioinguinal nerve?

• Dorsum of the entire foot
• Upper medial thigh
• Posterior calf
• Lateral leg

Q5. Which nerve classically carries the afferent limb of the cremasteric reflex from the upper medial thigh?

• Femoral nerve
• Obturator nerve
• Ilioinguinal nerve
• Tibial nerve

Q6. Which nerve supplies the efferent motor limb of the cremasteric reflex?

• Genital branch of the genitofemoral nerve
• Ilioinguinal nerve
• Saphenous nerve
• Lateral femoral cutaneous nerve

Q7. What is the relationship of the ilioinguinal nerve to the spermatic cord in males?

• It enters the canal only through the femoral ring
• It accompanies the spermatic cord through part of the canal without entering through the deep ring
• It lies inside the ductus deferens
• It is a branch of the testicular artery

Q8. What is the relationship of the ilioinguinal nerve to the round ligament in females?

• It accompanies the round ligament through part of the inguinal canal
• It passes through the obturator canal with it
• It ends in the ovary
• It forms the round ligament

Q9. Why can ilioinguinal and genitofemoral nerve symptoms overlap?

• Both pass through the obturator canal
• Their sensory territories overlap in the groin and external genital region
• Both are branches of the sciatic nerve
• Both supply quadriceps

Q10. Which feature helps distinguish the ilioinguinal nerve from the genital branch of the genitofemoral nerve in the inguinal region?

• Ilioinguinal supplies quadriceps
• Ilioinguinal does not pass through the deep inguinal ring
• The genital branch never enters the inguinal canal
• Ilioinguinal arises from the sacral plexus
