Question

Which of the following is the superior border of the femoral triangle?

BlackTom AI · Accepted Answer

To identify the superior border of the femoral triangle, we need to recall the standard anatomical borders.
Option 1: Inguinal ligament. This structure runs from the ASIS to the pubic tubercle and forms the superior boundary of the femoral triangle, separating the thigh from the abdomen. It is the correct answer because the triangle sits just inferior to this ligament.
Option 2: Adductor longus m. This muscle is positioned medially and forms the medial border of the femoral triangle, not the top edge.
Option 3: Sartorius m. This long, superficial muscle runs laterally across the thigh and constitutes the lateral border of the femoral triangle, not its superior border.
Option 4: Iliopsoas m. This muscle lies more deeply as part of the floor of the triangle (in conjunction with pectineus) and is not a border at the top, so it does not serve as the superior boundary.
Option 5: Pectineus m. While the pectineus contributes to the floor of the triangle and helps define its medial-to-anterior aspects, it is not a border at the superior edge.
In summary, the inguinal ligament uniquely serves as the superior boundary, while the other options correspond to medial, lateral, or deep boundaries and floor structures rather than the top edge.
