External Oblique Aponeurosis (EOA) ➢ The EOA serves as the superficial border of the inguinal canal and reflects posteriorly to form the inguinal ligament. ➢ The inguinal ligament extends form the anterior superior iliac(髂前上棘) to the pubic tubercle (inguinal ligament: it is formed as lateral edge of the aponeurosis of external oblique rolls upon itself and thickens into a cord, extending form the anterior superior iliac to the pubic tubercle.)
