Medial inguinal fossa-a direct inguinal hernia passes through the weak fascia in the medial inguinal fossa. this is the area between the medial and lateral umbilical folds (made of the obliterated umbilical artery and inferior epigastric vessels, respectively). a direct inguinal hernia does not pass through the deep inguinal ring or the lateral inguinal fossa-thats what an indirect hernia does. although its much more common for an indirect hernia to pass through the superficial inguinal ring, direct hernias could go through this ring too. however, the question is asking you to identify which region the hernia enters on the abdominal side, so superficial inguinal ring is not the correct answer. the supravesicular fossa is between the median and medial umbilical folds-it is formed where the peritoneum reflects from the anterior abdominal wall onto the bladder. potentially, a very rare external supravesicular hernia could form here.
