Anatomical Arrangement of the Arteries in the Lower Leg

Description

Running along the medial thigh, the femoral artery continues as the popliteal artery posterior to the knee before dividing into the anterior tibial and posterior tibial arteries for the leg and foot. Distally, the anterior tibial artery passes through the interosseous membrane to the anterior compartment, then becomes the dorsalis pedis artery on the dorsum of the foot, while the posterior tibial artery courses inferiorly and medially, giving rise to the fibular (peroneal) artery laterally and terminating as the medial and lateral plantar arteries. Superficial veins, including the great saphenous vein on the medial side and the small saphenous vein posteriorly, overlay the deep venous comitantes that accompany the tibial arteries. Clear color coding separates arterial inflow from venous return. For teaching lower limb circulation, this combined arterial and venous overlay is the workhorse view because it ties named vessels to surface pathways and common access points. The popliteal artery’s deep position in the fossa and the anterior tibial artery’s transition to dorsalis pedis explain why pedal pulse palpation works and why it fails in peripheral arterial disease. Venous anatomy matters too: the great saphenous vein’s long subcutaneous course makes it central to varicosities and a frequent conduit in bypass grafting, while deep vein thrombosis in the paired tibial veins can be clinically silent yet hazardous. Ideal for gross anatomy and cardiovascular blocks, this plate also supports vascular surgery and podiatry teaching when discussing tibial bypass targets, endovascular approaches, and distal revascularization planning. It fits well in patient education materials on peripheral arterial disease, diabetic foot ischemia, and chronic venous insufficiency, where correlating symptoms with a named vessel improves communication.
