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 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.
As they pass across the subcutaneous inguinal ring, they are connected together by delicate fibrous tissue, forming a fascia, called the intercrural fascia.. This intercrural fascia is continued down as a tubular prolongation around the spermatic cord and testis, and encloses them in a sheath; hence it is also called the external spermatic fascia.
Indirect inguinal hernias occur when abdominal contents protrude through the deep inguinal ring, lateral to the inferior epigastric vessels; this may be caused by failure of embryonic closure of the processus vaginalis. In the case of the female, the opening of the superficial inguinal ring is smaller than that of the male. As a result, the ...
These parts of the superficial fascia are most prominent in the lower aspect of the abdominal wall below the level of the umbilicus. Camper's fascia is continuous inferiorly with the superficial fascia of the thigh. Medial and inferior to the pubic tubercle, in the male, Scarpa's fascia changes as it continues over the scrotum and forms dartos ...
Superficial inguinal ring, a triangular opening that forms the exit of the inguinal canal Inguinal triangle , a region of the abdominal wall, also known by the eponym Hesselbach's triangle Lateral inguinal fossa , a shallow concave stretch of peritoneum on the deep surface of the anterior abdominal wall
The medial inguinal fossa is a depression located within the inguinal triangle on the peritoneal surface of the anterior abdominal wall between the ridges formed by the lateral umbilical fold and the medial umbilical ligament, corresponding to the superficial inguinal ring.
It inserts into the pubic crest and the pectineal line immediately behind the superficial inguinal ring. [1] It is usually conjoint with the tendon of the internal oblique muscle, but they may be separate as well. It forms the medial part of the posterior wall of the inguinal canal. [1]
