What is the superficial three -blade?

A superficial inguinal ring, known alternately as a subcutaneous or external inguinal ring, is a small opening between the layers of soft tissue in the lower abdominal wall. It is the farthest opening - closest skin - to the induinal channel, a tunnel that passes more nerves and reproductive vessels. This output from the inguinal channel is lower than its entrance, a deep three -bit ring. Although it is referred to as a ring, the surface inguinal ring has a triangular shape where it leaves the aponeurosis of the outer oblique muscle.

under the skin and fat covering the front of the pelvis are layers of tissue called aponeurosis. These flat, outstretched layers of fibrous tissue are associated with individual abdominal muscles - rectus of the abdomen, obliquus externus, obliquus internus and transversus abdomen - to the front or front aspect of the pelvis. Because every aponeurosis covers only part of the lower abdomen, crisage when they throw each other, are exposed between them as a superficial inguinal ring

One of these holes is the tan canal, whose input, a deep three -bit ring begins deep into the muscle of the transversus abdomen in a layer of tissue known as transversalis fascia. Fascia transversalis separates transverse abdominis, the deepest of the four abdominal muscles, from the peritoneum, a membrane containing the organs of the abdominal cavity. At the approximate center of the side of the three -way fold, the line from hipbons to hair, which defines where the foot meets the body, is where the deep inguinal ring opens into the inguinal channel.

The inguinal channel then passes down and inside at an angle roughly parallel to the class angle approaches the skin as descends. The transversus abdominus and the inner oblique muscles and their respective aponeurosis are close to the aponeurosis of the outer oblique muscle from the rear. In this tunnel there are two nerves, ilioinguinal and genitofemoral nerves, and a sperm cord in men and a round ligament in women. The sperm cord leads to the scrotum, so farWhat a round liga is a ligament that extends to a shy major and helps to hold the uterus in a pelvic cavity position. Due to the diameter of the sperm cord, the induinal channel in men has a more significant width than in women.

The creation of the lower output point of the three -wheel channel from which these blood vessels appear is a superficial class ring. The fibers of the lower edge of the aponeurosis appear external oblique and sit just above the class that follows a three -capable fold. The fibers, which share with these tissues along its borders, are known as cruure.
