Full Answer

The inguinal canal is an oblique passage through the lower part of anterior abdominal wall, according to ManAnatomy. The inguinal canal is about 1.5 inches long in adults. It extends from the deep inguinal ring, downward and medially, to the superficial inguinal ring.

There are four walls associated with the inguinal canal known as anterior, posterior, roof and floor, explains ManAnatomy. The anterior wall is formed along its entire length by the aponeuorsis of external oblique muscle. In its lateral part, it is reinforced by the origin of internal oblique from the inguinal ligament. No such reinforcement exists in the medial part. Therefore, the anterior wall is strongest in its lateral part. The posterior wall of the inguinal canal is formed along its entire length by the fascia transversalis.The roof of the canal is formed by the lowest fibers of internal oblique and transversus abdominis muscles. The floor of the canal is formed by the inguinal ligament.
