The superficial inguinal ring (subcutaneous inguinal ring or external inguinal ring) is an anatomical structure in the anterior wall of the mammalian abdomen. It is a triangular opening that forms the exit of the inguinal canal, which houses the ilioinguinal nerve , the genital branch of the genitofemoral nerve , and the spermatic cord (in men ...
The deep inguinal ring, which is the beginning of the inguinal canal, remains as an opening in the fascia transversalis, which forms the fascial inner wall of the spermatic cord. When the opening is larger than necessary for passage of the spermatic cord, the stage is set for an indirect inguinal hernia.
The spermatic cord in the male and the round ligament of the uterus in the female pass through the transversalis fascia at the deep inguinal ring, the entrance to the inguinal canal. This opening is not visible externally. In the male, the transverse fascia extends downwards as the internal spermatic fascia. [4]
The spermatic cord is the cord-like structure in males formed by the vas deferens (ductus deferens) and surrounding tissue that runs from the deep inguinal ring down to each testicle. Its serosal covering, the tunica vaginalis, is an extension of the peritoneum that passes through the transversalis fascia. Each testicle develops in the lower ...
The vas deferens traverses the inguinal canal to reach the pelvic cavity; it enters the pelvic cavity lateral to the inferior epigastric vessels. At the deep inguinal ring, the vas deferens diverges from the testicular vessels to pass medially to reach the base of the prostate posteriorly. [3]: 1297
The superficial inguinal ring is bounded below by the crest of the pubis; on either side by the margins of the opening in the aponeurosis, which are called the crura of the ring; and above, by a series of curved intercrural fibers.
It is named for Italian anatomist Antonio Scarpa. [2] His description of the membranous superficial fascia is vague in his 1809 hernia monograph. [3] Life-size illustrations included by Scarpa do not identify the layer even though some show all the other anatomical layers of the abdominal wall in the inguinal region.
The round ligament of the uterus originates at the uterine horns, in the parametrium.The round ligament exits the pelvis via the deep inguinal ring. [3] It passes through the inguinal canal to reach the labium majus, [4] [5] [2] inserting into the fibro-fatty substance of the labium majus.
