Dissection of male inguinal region and spermatic cord
Superficial inguinal ring; inguinal ligament; femoral sheath
The crura of the superficial inguinal ring (4) may be seen on either side of the spermatic cord. Above the level at which the cord emerges through the superficial ring the crura are covered by fibres of the intercrural fascia. Below the inguinal ligament the femoral sheath (13) has been exposed by removing the superficial inguinal lymph nodes, the cribriform fascia and part of the fascia lata which bounds the saphenous opening. The inferior part of the falciform margin of this opening has been retained (17).
