The deep inguinal ring is an opening in which fascia?

• A. Transversalis fascia
• B. Internal spermatic fascia
• C. External oblique aponeurosis
• D. Cremasteric fascia

Answer: (A)

The deep inguinal ring is an opening in the transversalis fascia, forming the internal entrance to the inguinal canal. It sits just above the midpoint of the inguinal ligament and lateral to the inferior epigastric vessels, through which the spermatic cord (in males) or the round ligament (in females) enters the canal. The superficial inguinal ring, by contrast, is an opening in the external oblique aponeurosis and serves as the exterior entrance. The internal spermatic fascia is a later covering of the cord derived from the transversalis fascia after it passes through the ring, and the cremasteric fascia arises from the internal oblique, not from the ring itself.
