The inguinal canal is a passage in the anterior abdominal wall. It begins at the deep inguinal ring, an opening in the transversalis fascia, and ends at the superficial inguinal ring, an opening in the external oblique aponeurosis. In males, it transmits the spermatic cord, while in females, it transmits the round ligament of the uterus. The canal runs obliquely downwards and medially through the abdominal wall.

The boundaries of the inguinal canal are defined by specific anatomical structures. The anterior wall is formed by the aponeurosis of the external oblique muscle, reinforced laterally by the conjoint tendon. The posterior wall is formed by the transversalis fascia, reinforced medially by the conjoint tendon. The roof is formed by the arching fibers of the internal oblique and transversus abdominis muscles. The floor is formed by the inguinal ligament and the lacunar ligament.

Hernias can occur in the inguinal canal, leading to conditions like inguinal hernias, which are common in both men and women. These hernias involve the protrusion of abdominal contents through a weak point in the canal. The inguinal canal plays a significant role in the descent of the testes during fetal development in males. Understanding its anatomy is crucial for diagnosing and treating various abdominal and pelvic conditions.
