The Lateral Side of the Foot
Where do the Lateral Superficial Lymphatic Vessels travel?
Either:
- Alongside the Small Saphenous Vein to enter the Popliteal Lymph Nodes
- Ascend in front of the Leg, crossing just below the Knee joint to join the Medial Superficial Lymphatic Vessels
Are there more Superficial or Deep Lymph Nodes?
