Conjoint tendon A weakening of the conjoint tendon can precipitate a direct inguinal hernia. A direct inguinal hernia will protrude through Hesselbach's triangle, whose borders are the rectus abdominis (medially), inferior epigastric artery and vein (superolaterally), and the inguinal ligament (inferiorly). The hernia will lie medial to the inferior epigastric artery. This is in contrast to an indirect inguinal hernia, which will protrude laterally to the inferior epigastric artery and is most commonly due to an embryological defect in the closure of the deep inguinal ring. Conjoint tendon The conjoint tendon (previously known as the inguinal aponeurotic falx) is a structure formed
Human leg skin there. Ilioinguinalis exits through the inguinal ring and supplies sensory branches to the skin above the pubic symphysis and the lateral portion of the scrotum. The genitofemoral nerve (L1, L2) leaves psoas major below the two former nerves, immediately divides into two branches that descends along the muscle's anterior side. The sensory femoral branch supplies the skin below the inguinal ligament, while the mixed genital branch supplies the skin and muscles around the sex organ. The lateral femoral cutaneous nerve (L2, L3) leaves psoas major laterally below the previous nerve, runs obliquely and laterally downward above the iliacus, exits
