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 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 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 femoral ring is the opening at the proximal, abdominal end of the femoral canal, [1] and represents the (superiorly directed/oriented [1]) base of the conically-shaped femoral canal. [1] The femoral ring is oval-shaped, [1] with its long diameter being directed transversely and measuring about 1.25 cm. [1] The opening of the femoral ring is ...
It is thinner and more membranous in character than the superficial fascia of Camper, and contains a considerable quantity of orange elastic fibers.. It is loosely connected by areolar tissue to the aponeurosis of the external oblique muscle, but in the midline it is more intimately adherent to the linea alba and the pubic symphysis, and in the male, it is prolonged on to the dorsum of the ...
Its base is concave, thin, and sharp, and forms the medial boundary of the femoral ring. Its apex corresponds to the pubic tubercle. Its posterior margin is attached to the pectineal line, and is continuous with the pectineal ligament. Its anterior margin is attached to the inguinal ligament. Its surfaces are directed upward and downward.

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 ...
