ABDOMEN: Inguinal Canal
, The Inguinal Canal
o This is an oblique passage through the lower part of the anterior abdominal wall.
o In the males, it allows structures to pass to and from the testis to the abdomen
and in females it allows the round ligament of the uterus to pass from the uterus
to the labium majus.
o It 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
o It lies parallel to and immediately above the inguinal ligament. o In the newborn
child, the deep ring lies almost directly posterior to the superficial ring so that the
,canal is considerably shorter at this age. Later, as the result of growth, the deep
ring moves laterally.
