What forms the superior border of the femoral triangle?

The superior border of the femoral triangle is formed by the inguinal ligament. This ligament runs from the anterior superior iliac spine to the pubic tubercle, creating a boundary that separates the trunk from the lower limb. The significance of the inguinal ligament lies in its role in providing structural support to the region and serving as an important landmark in anatomy. It delineates the femoral triangle, an important space through which major nerves, arteries, and veins pass to the thigh. Understanding the anatomy of the femoral triangle, including its borders, is crucial for various clinical assessments and procedures in the lower limb.
