Which structure is contained in the femoral triangle?

• A. Obturator nerve
• B. Deep femoral artery
• C. Internal pudendal artery
• D. Femoral artery

Answer: (D)

The femoral triangle houses the major neurovascular bundle of the thigh—nerve, artery, and vein—plus a lymphatic channel, often remembered as NAVL (Nerve, Artery, Vein, Lymphatics). The structure that lies within this triangle is the femoral artery, which runs alongside the vein and nerve just beneath the inguinal ligament. The obturator nerve is located in the medial thigh, not in the triangle; the internal pudendal artery is a pelvic vessel that travels to the perineum; and the deep femoral (profunda femoris) artery is a branch of the femoral artery, not one of the primary contents. So, the femoral artery is the structure contained in the femoral triangle.
