Deep in this location, the femoral artery in the pelvic cavity enters the lower limb. A band of skin is supplied by the lateral and anterior cutaneous branches of each of these nerves except the ilio-inguinal, which is a branch of the first lumbar nerve. The canal is potentially a weak area through which an inguinal hernia may occur. To prevent herniation of the abdominal contents inside the inguinal canal, the posterior wall of the canal contracts while the muscles of the anterior wall tighten to narrow the canal. Following the descent of the testicles into the scrotum, the processus vaginalis degenerates. Relating to this study, it should also be noted that variation in regional anatomy between the U.

The aponeurosis of the internal oblique muscle divides into anterior and posterior layers, which pass, respectively, in front of and behind the rectus muscle to reach the linea alba. The more complex part - the roof - is made of the combined fibers of the internal oblique and transversus abdominis muscle and aponeurosis including the conjoint tendon.
