What are tibial arteries?
The anterior tibial artery is the smaller terminating branch of the popliteal artery that arises from the lower border of the popliteus muscle. It passes forward through the interosseous membrane into the anterior compartment of the leg.
What is the posterior tibial artery used for?
The posterior tibial artery runs down the leg, just below the knee. It branches off from the popliteal artery and delivers freshly oxygenated blood to the leg's posterior compartment and the bottom portion of the foot.
Where does the tibial artery supply blood to?
Function. The posterior tibial artery supplies oxygenated blood to the posterior compartment of the leg and the plantar surface of the foot.
What are the three tibial arteries?
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).
What does the anterior tibial artery do?
The anterior tibial artery is responsible for the blood supply of the anterior crural compartment. At the anterior aspect of the ankle joint, the anterior tibial artery becomes the dorsalis pedis artery.
What is posterior tibial dysfunction?
Posterior tibial tendon dysfunction is one of the most common problems of the foot and ankle. It occurs when the posterior tibial tendon becomes inflamed or torn. As a result, the tendon may not be able to provide stability and support for the arch of the foot, resulting in flatfoot.

They originate from the foot veins behind the medial malleolus, which is part of the group of nerve tissue and muscle that surround the ankle joint. They run up the medial, or inner, sides of the calves to just below the knees. The posterior and anterior tibial veins are classified as deep calf veins that accompany the corresponding tibial arteries ...
Where are the posterior tibial veins located?
The posterior tibial veins, located in the lower legs, are considered among the major systemic veins of the human body. They originate from the foot veins behind the medial malleolus, which is part of the group ...
Which veins carry blood to the legs?
The posterior tibial veins carry blood from the fibular veins, up the legs, and to the popliteal veins. Whereas the tibial arteries supply oxygenated blood to the muscles, skin, and other tissues of the lower leg, the tibial veins carry oxygen-depleted blood away from the foot and lower leg, and back toward the heart.
What are the bifid veins in the lower leg?
The posterior and anterior tibial veins are classified as deep calf veins that accompany the corresponding tibial arteries of the lower legs. They are bifid veins, meaning that there are two veins for each artery.

The anterior tibial vein runs parallel to this artery throughout its course. It crosses the front part of the ankle ...
Which artery supplies blood to the dorsal surface of the foot?
As this artery goes across the interosseous membrane, it branches off into the dorsalis pedis artery, which supplies blood to the dorsal (top-most) surface of the foot. This further branches out into tarsal, lateral, and medial branches, where the artery culminates by intersecting the deep plantar and arcuate arteries.
Where do the anterior and posterior tibial veins form?
The anterior tibial veins then pierce the proximal end of the interosseous membrane and unite with the posterior tibial veins at the level of the distal border of the popliteus muscle. Thereby, the anterior and posterior tibial veins form the popliteal vein.
Where do the anterior tibial veins drain?
The anterior tibial veins receive tributaries from the dorsum of the foot and the anterior leg compartment, effectively draining these regions. They end at the level of the popliteus muscle by merging with the posterior tibial veins and forming the popliteal vein.
How long does it take to read a tibial vein?
Reading time: 2 minutes. Anterior tibial vein (Vena tibialis anterior) The anterior tibial veins are paired veins located in the anterior compartment of the leg. These veins accompany the anterior tibial artery, coursing over the anterior interosseous membrane of the leg.

Where does the anterior tibial artery go?
It moves downward and to the front, passing between the tibia and fibula, the two major bones of the lower leg, through a tough connective tissue called the interosseus membrane. 2 After passing through this membrane, the artery courses downward between two muscles of the front of the lower leg: the tibialis anterior and extensor digitorum longus muscles. From there, it accesses the front of the ankle joint, where it becomes the dorsalis pedis artery.
What causes a tibial artery to bleed?
Chronic cases arise due to excessive exertion in the muscles and are sometimes called “ exertional compartment syndrome .” In both cases, muscles in the anterior leg become inflamed, compressing the anterior tibial artery, and there may be internal bleeding, thus leading to a cascade of other symptoms. 5 These include pain and swelling, and, significantly, surrounding nerves can become damaged leading to loss of muscular function.
Which artery runs to the top of the foot?
Dorsalis pedis artery: Once the anterior tibial artery reaches the front of the ankle, it becomes the dorsalis pedis artery, which runs to the top surface of the foot before splitting off into a number of its own branches.
Which artery passes beneath the tendons of extensor digitorum longus?
Medial malleolar artery: Connecting with the posterior tibial artery, this artery emerges about 5 centimeters (cm). above the ankle joint, passing behind ankle tendons to terminate at the inner ankle. Lateral malleolar artery: This artery passes beneath the tendons of extensor digitorum longus as well as the fibularis tertius, ...

Which artery delivers oxygenated blood to the anterior (front-facing) compartment of the leg as well as the do?
A major branch of the popliteal artery, the anterior tibial artery delivers oxygenated blood to the anterior (front-facing) compartment of the leg as well as the dorsal (upper) surface of the foot. Paired with the anterior tibial vein along its downward course, it arises in the popliteal fossa just behind the knee, moves downward along the tibia and fibula (the major bones of the lower leg), and then crosses the anterior aspect (front portion) of the ankle joint. At this point it becomes the dorsalis pedis artery, which supplies the top of the foot. 1
What part of the foot do calcaneal tendon and calcaneus connect?
They perforate the flexor retinaculum and supply the skin over the calcaneal tendon and calcaneus, and the muscles of the medial part of the sole of the foot. They anastomose with medial malleolar arteries and calcaneal branches of the fibular artery.
What is the proximal part of the posterior tibial artery?
The proximal part of the posterior tibial artery as far as where the fibular artery branches off is often referred to as the tibiofibular trunk (or tibioperoneal trunk). The nutrient artery of tibia arises distally to the circumflex fibular artery.
What arteries surround the neck of the fibula?
The circumflex fibular artery arises immediately after the origin of the posterior tibial artery. It surrounds the neck of fibula and anastomoses with the inferior medial and lateral genicular and anterior tibial recurrent arteries. It supplies the proximal end of fibula.

The artery courses obliquely and laterally over the quadratus plantae muscle, passing deep to the abductor hallucis, flexor digitorum brevis and abductor digiti minimi muscles.
Where is the tibial nerve located?
The nerve crosses the posterior side of the artery’s origin and is located medial to the artery along its course. At the level of the flexor retinaculum, the tibial artery is found posterior to the veins and anterior to the posterior tibial nerve (branch of the tibial nerve).
Which artery delivers oxygenated blood to the posterior compartment of the lower leg?
Arising from the popliteal artery behind the knee, the posterior tibial artery (PTA) delivers oxygenated blood to the posterior compartment of the lower leg as well as the plantar surface of the foot (the flat portion between the heel and the ball of the foot). This artery perforates the soleus muscle, one of the major muscles of the calf, as it moves downwards in a parallel course to the posterior tibial vein.
Which artery connects to the dorsalis pedis artery?
As noted above, this artery splits into the medial and lateral plantar arteries at the level of the talus in the ankle. The former of these supplies the medial (middle) plantar (under) side of the foot, whereas the latter, larger artery, delivers to the heel and plantar portion closer to the side of the foot. As the artery connects with the dorsalis pedis artery, it creates the plantar arch that further supplies the toes and foot.
