Q1. What is the usual relationship of the iliohypogastric nerve to the subcostal nerve?
- It runs inside the subcostal artery
- It is a terminal branch of the subcostal nerve
- It joins the phrenic nerve
- It runs inferior and roughly parallel to the subcostal nerve
Q2. Which cutaneous branch of the iliohypogastric nerve supplies skin over the superolateral gluteal region?
- Genital branch
- Femoral branch
- Lateral cutaneous branch
- Anterior cutaneous branch
Q3. Where does the anterior cutaneous branch become superficial?
- Through the external oblique aponeurosis above the superficial inguinal ring
- Through the obturator canal
- Through the femoral canal
- Through the greater sciatic foramen
Q4. How does the iliohypogastric nerve relate to the iliac crest?
- It approaches the abdominal wall near the iliac crest
- It remains entirely above the twelfth rib
- It enters the acetabulum
- It passes through the iliac bone
Q5. Which nerve commonly courses inferior to and roughly parallel with the iliohypogastric nerve?
- Sciatic nerve
- Obturator nerve
- Ilioinguinal nerve
- Femoral nerve
Q6. Why is the plane between internal oblique and transversus abdominis important for the iliohypogastric nerve?
- It contains the spinal cord
- It contains the abdominal aorta
- It is a major neurovascular plane traversed by the nerve
- It forms the femoral sheath
Q7. Which sensory territory is associated with the lateral cutaneous branch?
- Posterior leg
- Superolateral gluteal skin
- Medial foot
- Palmar surface of the hand
Q8. Which sensory territory is associated with the anterior cutaneous branch?
- Lateral foot
- Perianal skin
- Suprapubic skin
- Posterior scalp
Q9. Why can the iliohypogastric nerve contribute to abdominal wall weakness if injured?
- It is the main motor nerve of quadriceps
- It innervates the diaphragm
- It supplies only skin
- It supplies motor fibers to internal oblique and transversus abdominis
Q10. Which anatomical feature most clearly distinguishes the iliohypogastric nerve from the genitofemoral nerve on psoas major?
- It exits through the greater sciatic foramen
- It emerges laterally from psoas rather than descending on its anterior surface
- It passes through the obturator canal
- It is contained within the femoral sheath
