Answer

The inguinal ligament bridges the space between the pubic tubercle and the anterior superior iliac spine and rotates posteriorly and then superiorly to form a shelving edge. It is the caudad edge of the external oblique aponeurosis. This ligament revolves medially to create the lacunar ligament, which inserts on the pubis and courses medially and superiorly toward the midline. The external oblique aponeurosis has a triangular opening with a superior apex, through which the cord enters the inguinal canal.
