Overview. The lower limb is supplied by the femoral artery, which receives blood from the abdominal aorta via the external iliac artery. The femoral artery lies at the base of the femoral triangle, between the femoral nerve and the femoral vein.
What is the femoral artery? The femoral artery is a major blood vessel in your body. It carries blood from the bottom of your abdomen down through your lower limbs.
Terms in this set (34) –The femoral artery is a large artery in the thigh and the main arterial supply to the lower limb. -It enters the thigh from behind the inguinal ligament as the common femoral artery, a continuation of the external iliac artery.
Arteries (in red) are the blood vessels that deliver blood to the body. Veins (in blue) are the blood vessels that return blood to the heart. Deep veins, located in the center of the leg near the leg bones, are enclosed by muscle. The iliac, femoral, popliteal and tibial (calf) veins are the deep veins in the legs.
The lower extremity includes the hip, knee, and ankle joints, and the bones of the thigh, leg, and foot. Many people refer to the lower extremity as the leg. In fact, the leg is the part of the body between the knee and ankle joints. The proper way to describe the lower limb is the lower extremity.
There are two major nerves in the lower leg: the fibular nerve and tibial nerve. They also connect to form a sensory nerve known as the sural nerve.
Arcuate artery (arteria arcuata) The arcuate artery of the foot is a branch of the dorsalis pedis artery. It courses on the dorsum of the foot, passing laterally over the bases of the metatarsal bones beneath the tendons of the extensor digitorum brevis muscle.
The three arteries of the lower leg are the peroneal artery, anterior tibial artery, and posterior tibial artery (the proximal aspect of the posterior artery is also know as the tibial-peroneal trunk).
The anterior tibial artery is one of the terminal branches of the popliteal artery. It arises below the popliteal fossa, in the posterior (flexor) compartment of the leg. … The artery terminates at the level of the ankle joint, where it gives off its terminal branch, the dorsalis pedis artery.
Blood Supply and Lymphatics The blood supply of the lateral leg compartment is described below going proximally to distally: The anterior tibial artery gives off the superior lateral fibular artery and the inferior lateral fibular artery, which supply the proximal fibularis muscles.
The femoral artery also gives rise to the genicular artery, which provides blood to the region of the knee. As the femoral artery passes posterior to the knee near the popliteal fossa, it is called the popliteal artery. The popliteal artery branches into the anterior and posterior tibial arteries.
Plantar arteries: The plantar arteries—lateral, medial, and deep—form a looping web of arteries across the foot and down through each toe. They eventually unite with the dorsalis pedis artery. Dorsalis pedis: This artery supplies blood to the surface of the foot as a continuation of the anterior tibial artery.
Important veins of the leg include the internal and external iliac veins, femoral vein, saphenous vein, popliteal vein, tibial vein, and the venous arch of the foot.
The valves close when blood starts to flow in one direction, so that blood in the veins can only flow in the direction back to the heart, which is up the legs. When you squeeze your leg muscles to walk, stand, kick, and move about, the muscles squeeze the veins and force the blood to get moving.
Great saphenous vein (GSV) – The GSV is the large superficial vein of the leg and the longest vein in the entire body. It can be found along the length of the lower limb, returning blood from the thigh, calf, and foot to the deep femoral vein at the femoral triangle. The femoral triangle is located in the upper thigh.
The lower limb contains 30 bones. These are the femur, patella, tibia, fibula, tarsal bones, metatarsal bones, and phalanges (see Figure 6.51). The femur is the single bone of the thigh. The patella is the kneecap and articulates with the distal femur.
Chapter Review. The lower limb is divided into three regions. These are the thigh, located between the hip and knee joints; the leg, located between the knee and ankle joints; and distal to the ankle, the foot. There are 30 bones in each lower limb.
The leg region is the part of the lower limb that lies between the knee and the rounded medial and lateral prominences (medial and lateral malleoli) that flank the ankle joint. It contains the tibia (shin bone) and fibula (Latin word meaning “buckle”) and connects the knee and foot.
The femoral nerve is the major nerve that serves the tissues of the thigh and leg, including the muscles and skin. While the much larger sciatic nerve also passes through the thigh on its way to the lower leg and foot, only the femoral nerve innervates the tissues of the thigh.
In the leg, the tibial nerve supplies gastrocnemius, plantaris, soleus, and all three of the deep flexor muscles, including tibialis posterior.
The femoral nerve is located in the pelvis and goes down the front of the leg. It helps the muscles move the hip and straighten the leg. It provides feeling (sensation) to the front of the thigh and part of the lower leg.
The interlobar arteries are vessels of the renal circulation which supply the renal lobes. The interlobar arteries branch from the lobar arteries which branch from the segmental arteries, from the renal artery.
vasa recta Thin-walled blood vessels that branch from the efferent arterioles leaving each glomerulus in the vertebrate kidney (see nephron). The vasa recta form U-shaped loops adjacent to the loop of Henle and eventually drain into the renal vein.
Cortical radial arteries, formerly known as interlobular arteries, are renal blood vessels given off at right angles from the side of the arcuate arteries looking toward the cortical substance. … In their outward course, they give off lateral branches, which are the afferent arterioles that supply the renal corpuscles.
Medical Definition of peroneal vein : any of several veins that drain the muscles in the lateral and posterior parts of the leg, accompany the peroneal artery, and empty into the posterior tibial veins about two-thirds of the way up the leg.
In terms of arterial supply, the upper limb has 5 main vessels, the: subclavian, axillary, brachial, radial, and ulnar arteries. The subclavian, axillary and brachial arteries are continuous with one another, with the brachial artery bifurcating into the radial and ulnar arteries which later converge in the hand.
Blood Supply and Lymphatics The posterior compartment of the leg receives vascular supply from the posterior tibial artery.  This artery is a continuation of the popliteal artery, with the latter arising from the femoral artery.

In anatomy, the fibular artery, also known as the peroneal artery, supplies blood to the lateral compartment of the leg. It arises from the tibial-fibular trunk.
Put simply, the femoral artery originates in the groin and runs down each leg, stopping right around the knee. (At the knee, the femoral artery becomes the popliteal artery).
The femoral artery is a continuation of the external iliac artery and constitutes the major blood supply to the lower limb. … The femoral artery and its branches supply most of the thigh as well as the entirety of the leg and foot.
The deep femoral artery supplies the posterior compartment.
The popliteal vein forms from the union of the anterior and posterior tibial veins. The popliteal vein becomes the femoral vein as it emerges from the knee.
Primarily, the anterior tibial artery serves to deliver oxygenated blood to the front portion of the lower leg, which is called the “anterior crural compartment.” As such, and via its branches, it supplies nerve, muscular, and other tissues of the front of the lower-leg, as well as the skin.
The blood supply to the diaphragm is from the superior phrenic, musculophrenic, inferior phrenic, pericardiacophrenic, and lower internal intercostal arteries. The superior phrenic arteries arise from the thoracic aorta.
The dorsalis pedis artery (dorsal artery of foot), is a blood vessel of the lower limb that carries oxygenated blood to the dorsal surface of the foot. It arises at the anterior aspect of the ankle joint and is a continuation of the anterior tibial artery.
Plantar metatarsal veins – Venae metatarsales plantares.
The plantar veins are connected like a bowstring between the base of the fourth metatarsal and the medial malleolus.
There are seven deep veins located in the lower extremities. Due to the fact that deep veins collectively carry the majority of your blood, an obstruction can become life-threatening.
- Arteries carry blood away from your heart.
- Veins carry blood back toward your heart.
- Capillaries, the smallest blood vessels, connect arteries and veins.
