Sample itemA surgeon repairing a hernia notes the deep inguinal ring lies lateral to the inferior epigastric artery. Through which structure's opening is the deep ring formed?
Original practice item, not a recalled exam question. Nothing here is recorded.
The answer and the reasoning
B. Transversalis fascia
The deep inguinal ring is an opening in the transversalis fascia, lateral to the inferior epigastric vessels. The superficial ring is a split in the external oblique aponeurosis. Indirect hernias enter through the deep ring.
Option by option
A. Conjoint tendon
The conjoint tendon forms the posterior wall medially and not the deep ring.
B. Transversalis fascia (correct)
Correct. The deep ring is a defect in the transversalis fascia.
C. Internal oblique muscle
The internal oblique arches over the canal and does not form the ring.
D. External oblique aponeurosis
The superficial ring is a gap in the external oblique aponeurosis.
