Answer

The femoral sheath, with contributions from the transversalis, pectineus, psoas, and iliacus fasciae, has three compartments. A femoral hernia most often occurs in the most medial compartment. The femoral canal is bounded laterally by the femoral vein. The medial margin is the transversus abdominis aponeurosis insertion and transversalis fascia. The femoral canal holds lymphatic channels and lymph nodes.
