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.
The protrusion of peritoneum through the internal inguinal ring can be considered an incomplete obliteration of the processus. In an indirect inguinal hernia, the protrusion passes through the deep inguinal ring and is located lateral to the inferior epigastric artery. Hence, the conjoint tendon is not weakened. There are three main types ...
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 ...
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.
Inguinal triangle is labeled in green. Borders: inferior epigastric artery and vein: labeled at center left, and run from upper right to bottom center. inguinal ligament: not labeled on diagram, but runs a similar path to the inguinal aponeurotic falx, labeled at bottom. rectus abdominis muscle: runs from upper left to bottom left.
The femoral branch passes underneath the inguinal ligament, travelling through the lateral muscular compartment of the femoral sheath where it innervates skin of the upper leg. Passing through the cribriform fascia of the saphenous opening of the fascia lata of the thigh, it then supplies the skin of the upper, anterior and medial side of thigh ...
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.
