The external iliac becomes the femoral artery when it crosses under the inguinal ligament In the femoral triangle, the profunda femoris artery arises from the femoral artery It gives three main branches: Perforating branches Lateral femoral circumflex artery Medial femoral circumflex artery The femoral artery moves through the adductor hiatus The femoral artery is now known as the popliteal artery .

Clinical Relevance: Accessing the Femoral Artery The femoral artery is located superficially within the femoral triangle, and is thus easy to access. This makes it suitable for a range of clinical procedures. One such procedure is coronary angiography.

In the Leg Popliteal artery Terminates by dividing into Anterior tibial artery Tibioperoneal trunk which bifurcates into Posterior tibial Fibular arteries Anterior tibial artery: runs down the entire length of the leg, and into the foot, where it becomes the dorsalis pedis artery . Posterior tibial artery – continues inferiorly. It enters the sole of the foot via the tarsal tunnel , accompanying the tibial nerve. Fibular (peroneal) artery – supply muscles in the lateral compartment of the leg.

Clinical Relevance: Popliteal Aneurysm The popliteal fascia (the roof of the popliteal fossa) is tough and non-extensible, and so an aneurysm of the popliteal artery has consequences for the other contents of the popliteal fossa. The tibial nerve is particularly susceptible to compression from the popliteal artery. An aneurysm of the popliteal artery can be detected by an obvious palpable pulsation in the popliteal fossa. An arterial bruit may be heard on auscultation.

In the Foot Arterial supply to the foot is delivered via two arteries: Dorsalis pedis A continuation of the anterior tibial artery Anastomoses with the lateral plantar Posterior tibial Enters the sole of the foot through the tarsal tunnel. Splits into the lateral and medial plantar arteries. supply the plantar side of the foot, and contributes to the supply of the toes via the deep plantar arch .

Clinical Relevance: Pulse Points in the Lower Limb There are four main pulse points in the lower limb; femoral, popliteal, posterior tibial and dorsalis pedis.

Venous Drainage of the Lower Limb
Image of page 26
Venous Drainage of the Lower Limb Can be divided into two groups – deep and superficial Deep veins are located underneath the deep fascia of the lower limb, accompanying the major arteries. Superficial veins are found in the subcutaneous tissue. They eventually drain into the deep veins.
Image of page 27
Deep Veins of the Lower Limb Often, the artery and vein are located within the same vascular sheath – so that the arterial pulsations aid the venous return. The main venous structure of the foot is the dorsal venous arch mostly drains into the superficial veins.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
