All of the following statements regarding inguinal canal are true, EXCEPT:
Deep inguinal ring is an oval opening in the fascia transversalis, that lies about 1/2 inch above the inguinal ligament midway between the anterior superior iliac spine and pubis symphysis. Medial to it lies the inferior epigastric vessels.Superficial inguinal ring is a triangular gap in the external oblique aponeurosis, which lies above and medial to the pubic tubercle.Ref: Clinical anatomy for Medical Students By Richard S Snell, 6th Edition, Page 149 ; B.D.Chaurasia's Human Anatomy, 5th Edition, Volume 2, Page 224
Inguinal ligament forms posterior wall of inguinal canal
Internal oblique forms both anterior and posterior wall
