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 inguinal ligament (/ ˈ ɪ ŋ ɡ w ɪ n ə l / [1] [2]), also known as Poupart's ligament or groin ligament, is a band running from the pubic tubercle to the anterior superior iliac spine. It forms the base of the inguinal canal through which an indirect inguinal hernia may develop.
Femoral nerve and its terminal branches - The nerve enters the femoral triangle by passing beneath the inguinal ligament, just lateral to the femoral artery. In the thigh, the nerve lies in a groove between iliacus muscle and psoas major muscles, outside the femoral sheath, and lateral to the femoral artery.
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 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 retroinguinal space (or Bogros' space) is the extraperitoneal space situated deep to the inguinal ligament. It's limited by the fascia transversalis anteriorly, the peritoneum posteriorly and the iliac fascia laterally. This preperitoneal space communicates with prevesical space of Retzius. It is divided into two compartments.
Variations in origin and course of obturator artery. (Obturator canal not labeled, but visible at bottom center of each diagram.) The obturator canal is formed between the obturator membrane and the pelvis. [1] The obturator artery, obturator vein, and obturator nerve all travel through the canal.
It passes outward on the psoas major muscle, and pierces the fascia transversalis, or passes through the deep inguinal ring. It then descends within the spermatic cord . In males, it passes through to the scrotum , where it supplies the cremaster , dartos muscle and gives a few filaments to the skin of the scrotum.
