Canalis Inguinalis, commonly known as the inguinal canal, is a passage through the lower abdominal wall between the inguinal ligament and the pubic bone. There are several synonyms for this anatomical structure, including Michel's canal, abdominal inguinal ring canal, and spermatic cord canal. The inguinal canal plays an important role in the anatomy of both males and females, as it contains the spermatic cord in males and the round ligament in females. This structure is also susceptible to hernias, which occur when abdominal contents protrude through the weak point in the wall of the inguinal canal. Understanding the anatomy and synonyms of the canalis inguinalis is essential for medical professionals to correctly diagnose and treat hernias and other abdominal conditions.
