Covers the inguinal canal as a passage in the lower anterior abdominal wall, carrying the spermatic cord in males or the round ligament of the uterus in females. It gives the canal's length and position relative to the inguinal ligament, then its floor, roof, and anterior and posterior walls. It notes why the canal is a weak point that can allow an inguinal hernia, and lists the contents in males and females in a comparison table.
