General introduction
The lower limb is divided intoof the thigh
Cutaneous branch:
Anterior femoral cutaneous nerve
Saphenous nerve (accompanies the femoral artery at thigh, and accompanies the great saphenous vein at leg)
Femoral artery:
Muscular branches
Deep femoral artery:
lateral and medial femoral circumflex a.
Perforating arteries: 3 or 4 arteries
第九页，共七十四页。
Thigh---anterior and medial region (2)
Deep structures
Contents of the femoral triangle
Femoral sheath and femoral canal
Femoral canal is the medial compartment of the femoral sheath, contains deep lymph nodes and fat tissue. Its superior opening called femoral ring. Boundaries:
Laterally: femoral vein
Medially: lacunar ligament
Anteriorly: inguinal ligament
Posteriorly: pectineal ligament (of Cooper)
Femoral hernia: contents of abdomen protrude through the femoral ring into the femoral canal
