Intermediate Genitofemoral Nerve Quiz

Q1. How does the genitofemoral nerve relate to psoas major during its course?

• It travels through the psoas tendon into the lesser trochanter
• It remains entirely lateral to psoas major
• It pierces psoas major and descends on its anterior surface
• It passes only along the medial border without piercing it

Q2. Which genitofemoral branch forms the efferent limb of the cremasteric reflex?

• Lateral femoral cutaneous nerve
• Femoral branch
• Saphenous nerve
• Genital branch

Q3. Which nerve is classically associated with the afferent limb of the cremasteric reflex from the upper medial thigh?

• Obturator nerve
• Sciatic nerve
• Femoral nerve
• Ilioinguinal nerve

Q4. Through which opening does the genital branch enter the inguinal canal in males?

• Superficial inguinal ring from outside
• Obturator canal
• Deep inguinal ring
• Femoral ring

Q5. What is the relationship of the femoral branch to the femoral sheath?

• It enters the femoral sheath region near the femoral artery
• It passes through the femoral canal medial to the vein
• It lies within the femoral nerve
• It enters the obturator canal

Q6. What sensory territory is supplied by the genital branch in males in addition to its cremasteric motor supply?

• Lateral leg and dorsum of foot
• Sole of the foot
• Part of the anterior scrotal skin
• Entire posterior thigh

Q7. In females, where does the genital branch distribute?

• Posterior thigh and popliteal fossa
• Gluteal region
• Medial leg and foot
• Mons pubis and labium majus

Q8. Which structure is closely related to the genitofemoral nerve as it descends on psoas major?

• Portal vein within the hepatoduodenal ligament
• Great saphenous vein at the ankle
• Axillary artery
• Retroperitoneal ureter and gonadal vessels

Q9. Why can the genitofemoral nerve be confused clinically with the ilioinguinal nerve?

• Their sensory territories overlap in the groin and genital region
• They are branches of the sciatic nerve
• Both supply quadriceps femoris
• They have identical root values and courses

Q10. Which feature best distinguishes the femoral branch of the genitofemoral nerve from the femoral nerve itself?

• Both are identical nerves with different names
• The femoral branch supplies quadriceps motor fibers
• The femoral nerve arises only from L1
• The genitofemoral femoral branch is a small sensory nerve, unlike the large mixed femoral nerve
