Dissection of female inguinal region

Femoral septum and associated lymph node, left side viewed from above

The specimen shown previously has been turned and is now viewed from above and inside. The pubic symphysis lies next to the right. Peritoneum and fascia have been removed to reveal the external iliac vessels (3,5) as they pass downward through the vascular compartment deep to the inguinal ligament (2). A thickened band of fascia known as the deep femoral arch, which is fused to the inguinal ligament has been elevated. The femoral septum (11) is visible medial to the external iliac vein. The cribriform nature of this septum is evident in the photograph. It forms the base of the femoral canal and is penetrated by lymphatic vessels which enter the lymphatic node (of Cloquet) (14) which is located just above the septum.
