The transversus abdominis has been elevated along its lower border. The round ligament has been lifted away from the posterior wall of the inguinal canal.

1. Transversus abdominis muscle
2. Ligamentum teres (of uterus) (encased in fascial continuation from transversalis fascia)
3. Internal oblique muscle (reflected)
4. Inferior epigastric artery
5. Conjoint tendon (falx inguinalis)
6. Interfoveolar ligament (muscle fibers present)
7. Branch of inferior epigastric artery
8. Right pointer: Inguinal ligament Left pointer: Pubic tubercle
9. Ligamentum teres (of uterus) (extending downward into labium majus)
10. Internal oblique muscle (origin)
11. Transversalis fascia
12. Cremaster muscle (upper pointer indicates nerve supply, genital branch of genitofemoral nerve)
13. Upper pointer: Inguinal ligament Lower pointer: Deep femoral arch (consisting of fibers associated with transversalis fascia)
14. Superficial inguinal lymph node (retracted downward)
15. Femoral sheath (pointer overlies femoral vein)
16. Femoral canal (note lymphatic vessels passing through canal)
