Superficial inguinal ring is a defect in the:
a) Internal oblique aponeurosis
b) External oblique aponeurosis
c) Transverse abdominis aponeurosis
d) Internal oblique muscle
Correct Answer - B
The inguinal canal is an oblique passage through the lower part of
the anterior abdominal wall.
The canal is about 1.5 in. (4 cm) long in the adult and extends from
the deep inguinal ring, a hole in the fascia transversalis, downward
and medially to the superficial inguinal ring, a hole in the
aponeurosis of the external oblique muscle. In the males, it allows
structures to pass to and from the testis to the abdomen.
In females it allows the round ligament of the uterus to pass from the
uterus to the labium majus.
