is a canal, about two inches in length, proceeding obliquely downwards, inwards and forwards at the lower part of the abdomen; through which passes the spermatic cord, in men, and the round ligament of the uterus in women. This canal is formed, inferiorly and anteriorly, by the aponeurosis of the greater oblique muscle; posteriorly by the fascia transversalis, which is joined to the preceding aponeurosis, and forms with it a deep channel, into which are received the lesser oblique and transversalis muscles. The inguinal canal has two apertures: the one, the lower and inner, is called the inguinal or abdominal ring. It is bounded by two strong tendinous pillars which fix it- the innermost to the symphysis, the outermost to the spine of the pubis. The upper and outer aperture is formed by the fascia transversalis. From the edge of this aperture arises a membranous funnel, - a prolongation of the fascia transversalis, - which receives the spermatic vessels; forms their proper sheath, and accompanies them as far as the testicle. On its inside lies the epigastric artery. Above it, is the lower edge of the transversalis muscle: and, below, it is bounded by the channel of the greater oblique. By following the oblique direction of this canal, and passing, consequently, on the outside of the epigastric artery, the viscera are displaced, so as to constitute internal inguinal hernia.

A c. about an inch and a half long, running obliquely downward and inward from the internal abdominal ring to the external abdominal ring. It transmits the spermatic cord in the male and the round ligament in the female, and constitutes the channel by which an inguinal hernia descends
