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
Inguinal lymph nodes nodes. They lie medial to the femoral vein under the cribriform fascia. The uppermost node is in the groin, under the inguinal ligament, and is called Cloquet's node (also Rosenmuller's node). This node is named for French surgeon Jules Germain Cloquet, or for German anatomist Johann Christian Rosenmüller. It can also be considered as the lowest of the external iliac lymph nodes. Cloquet's node is also considered as a potential sentinel lymph node. The deep inguinal lymph nodes drain superiorly to the external iliac lymph nodes, then to the pelvic lymph nodes and on to the paraaortic lymph nodes. The
