Pull the inferior portion of anterior abdominal wall anteriorly and inferiorly to examine the inner surface of the anterior abdominal wall . Just superior to the midpoint of the inguinal ligament, identify the deep inguinal ring which is covered by the parietal peritoneum [seen from inside the abdominal cavity].
Remove the peritoneum and extraperitoneal adipose tissue around the deep inguinal ring to expose the transversalis fascia. Confirm the location of the deep inguinal ring just lateral to the inferior epigastric artery and vein.In the male, identify the ductus deferens and the associated blood vessels and nerves, that pass through the deep inguinal ring into the abdominal cavity. In the female, identify the round ligament of the uterus with associated vessels that pass via the inguinal canal to the labia majora.
