Inguinal hernia which are defined by their relationship to the inferior epigastric vessels. Direct inguinal hernias occur medial to the inferior epigastric vessels when abdominal contents herniate through a weak spot in the fascia of the posterior wall of the inguinal canal, which is formed by the transversalis fascia. Indirect inguinal hernias occur when abdominal contents protrude through the deep inguinal ring, lateral to the inferior epigastric vessels; this may be caused by failure of embryonic closure of the processus vaginalis. In the case of the female, the opening of the superficial inguinal ring is smaller than that of the male. As
Deep inguinal ring by the inferior epigastric vessels. It transmits the spermatic cord in the male and the round ligament of the uterus in the female. From its circumference a thin funnel-shaped membrane, the infundibuliform fascia, is continued around the cord and testis, enclosing them in a distinct covering. Deep inguinal ring The deep inguinal ring (internal or deep abdominal ring, abdominal inguinal ring, internal inguinal ring) is the entrance to the inguinal canal. The surface marking of the deep inguinal ring is classically described as half an inch above the midpoint of the inguinal ligament . However, the surface anatomy of the
