Superficial Inguinal Ring

Deep Inguinal Ring

Inguinal Canal

The passage of the testes or the round ligament of the uterus through the anterior body wall creates the Inguinal Canal. This canal passes obliquely between the deep and superficial inguinal rings. The walls of the inguinal canal include the transversalis fascia, preperitoneal connective tissue, peritoneum, anterior abdominal wall muscles or their representatives, and the inguinal ligament and its representatives. The Deep Inguinal Ring is an outpouching of the transversalis fascia located lateral to the inferior epigastric artery in the lateral inguinal fossa. The deep inguinal ring serves as a conduit for the vas deferens, round ligament, autonomic nerves, lymphatics, and gonadal vessels. The Superficial Inguinal Ring is a triangular cleft in the aponeurosis of the external abdominal oblique. It is bordered by strong bands of the aponeurosis, the medial crus attached to the crest of the pubis, and the lateral crus attached to the pubic tubercle. The superficial inguinal ring lies superior and lateral to the pubic tubercle.
