| Name = Superficial inguinal ring | Latin = Anulus inguinalis superficialis | Image = Gray1227.png | Caption = Front of abdomen, showing surface markings for arteries and inguinal canal (superficial inguinal ring labeled as subcutaneous inguinal ring at lower left) | Image2 = Gray393.png | Caption2 = The superficial inguinal ring. | System = }} The superficial inguinal ring (subcutaneous inguinal ring or external inguinal ring) is an anatomical structure in the anterior wall of the mammalian abdomen. It is a triangular opening that forms the exit of the inguinal canal, which houses the ilioinguinal nerve, the genital branch of the genitofemoral nerve, and the spermatic cord (in men) or the round ligament (in women). At the other end of the canal, the deep inguinal ring forms the entrance.[1] It is found within the aponeurosis of the external oblique, immediately above the pubic crest, 1 centimeter above and superolateral to the pubic tubercle. It has the following boundaries—medial crura by pubic crest, lateral crura by pubic tubercle and inferiorly by inguinal ligament.[2] Clinical significanceThe superficial ring is palpable[3] under normal conditions. It becomes dilated in a condition called athletic pubalgia. Abdominal contents may protrude through the ring in inguinal hernia. GallerySee also
