All of the following statements regarding inguinal canal are true, EXCEPT:: (A) Inguinal ligament forms posterior wall of inguinal canal, (B) Internal oblique forms both anterior and posterior wall, (C) Deep inguinal ring is an opening in transversalis abdominis, (D) Superficial inguinal ring is found in external oblique aponeurosis
Answer is C. 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
