Which nerve contributes to sensation of the anterior thigh via its anterior branches?

• A. Femoral nerve
• B. Obturator nerve
• C. Iliohypogastric nerve
• D. Genitofemoral nerve

Answer: (A)

Sensation on the front of the thigh comes mainly from the femoral nerve through its anterior cutaneous branches. After the femoral nerve enters the thigh beneath the inguinal ligament, it gives off these anterior branches that innervate the skin of the anterior thigh. The other nerves have different territories: the obturator nerve supplies the medial thigh, the iliohypogastric nerve covers the suprapubic region, and the genitofemoral nerve has only a small femoral branch that supplies a limited area on the upper anterior thigh. Thus, the femoral nerve is the primary source of anterior thigh sensation via its anterior branches.
