Arteries of the Legs, Gross Anatomy

Description

Running from the proximal thigh to the dorsum of the foot, the femoral artery continues distally through the adductor hiatus as the popliteal artery, then divides into anterior and posterior tibial arteries that track along the crus beside the tibia and fibula. The anterior tibial artery passes to the anterior compartment and becomes the dorsalis pedis artery over the tarsal region, while the posterior tibial artery courses posterior to the medial malleolus toward the plantar foot. Deep muscular branches and cutaneous perforators are shown in relation to the femur, patella, tibia (medial) and fibula (lateral), with the arterial tree consistently remaining anterior, posterior, medial, or lateral to these bony landmarks. Bony reference points matter. Clinical teaching often hinges on where you can palpate, compress, or inadvertently injure these vessels. The femoral pulse is taken just inferior to the inguinal ligament, and the artery’s passage through the adductor canal explains why distal perfusion can be threatened by superficial femoral artery occlusion while proximal pulses persist. At the knee, the popliteal artery lies deep in the popliteal fossa against the distal femur and posterior capsule, a relationship that informs the vascular urgency of knee dislocation and posterior tibial plateau fractures. Distally, the conversion of anterior tibial to dorsalis pedis supports bedside assessment of peripheral arterial disease, and the posterior tibial artery’s course behind the medial malleolus guides both pulse exam and surgical exposure. Use this plate when you need a clean arterial map for lower-limb anatomy labs, vascular surgery and interventional radiology teaching files, or textbook figures on limb perfusion, compartment anatomy, and pulse points. It also fits clinical patient-education material on claudication, acute limb ischemia, and bypass targets, where the named vessels must remain anatomically consistent against tibia, fibula, and foot bones.
