Superficial inguinal ring :The superficial inguinal ring is an opening (defect) in the aponeurosis of external oblique muscle.Surface marking: Just above and medial to the pubic tubercle.Shape: Triangular.Fascial prolongation from the margin of superficial inguinal ring is - external spermatic fascia.
