Which of the following is NOT located in the femoral triangle?

Question

BlackTom AI · Accepted Answer

To start, let’s lay out the anatomical context: the femoral triangle is an anatomical space in the upper thigh bounded by the inguinal ligament, the adductor longus, and the sartorius, and its contents are classically summarized by the acronym NAV (Nerve, Artery, Vein).
Option 1: Lesser saphenous v. This vein runs along the posterior aspect of the leg and drains into the popliteal vein behind the knee. It does not travel within the femoral triangle in the thigh; therefore, it is not located in the femoral triangle.
Option 2: Femoral a. The femoral artery is one of the key contents of the femoral triangle, passing deep to the inguinal ligament and within the triangle before transitioning to the adductor canal. Thus, it is located in the femoral triangle.
Option 3: Femoral v. The femoral vein accompanies the femoral artery within the triangle and is a classic component of the NAV rule. It is located in the femoral triangle.
Option 4: Femoral n. The femoral nerve travels lateral to the artery and vein within the femoral triangle and is another standard content.
In summary, options 2, 3, and 4 describe structures that anatomically reside in the femoral triangle, while the lesser saphenous vein (option 1) does not. The question asks which is NOT located in the femoral triangle, so the incorrect choice is the only one that lies outside that region.
