, 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.

Structure

The fibular artery arises from the bifurcation of tibial-fibular trunk into the fibular and posterior tibial arteries in the upper part of the leg proper, just below the knee. It runs towards the foot in the deep posterior compartment of the leg, just medial to the

fibula The fibula (: fibulae or fibulas) or calf bone is a leg bone on the lateral side of the tibia, to which it is connected above and below. It is the smaller of the two bones and, in proportion to its length, the most slender of all the long bones. ...

. It supplies a perforating branch to both the lateral and anterior compartments of the leg; it also provides a nutrient artery to the fibula. Some sources claim that the fibular artery arises directly from the posterior tibial artery, but vascular and plastic surgeons note the clinical significance of the tibial-fibular trunk. The fibular artery is accompanied by small veins (

venae comitantes Vena comitans (Latin for accompanying vein, also known as a satellite vein) refers to a vein that is usually paired, with both veins lying on the sides of an artery. Because they are generally found in pairs, they are often referred to by their ...

fibular veins In anatomy, the fibular veins (also known as peroneal veins) are accompanying veins (venae comitantes) of the fibular artery. Structure The fibular veins are deep veins that help carry blood from the lateral compartment of the leg. They drain ...

Nomenclature

At one point in its history, both the Greek term ''perone'' and the Latin term ''fibula'' were competing to describe the smaller bone of the leg. Many of the arteries, veins, nerves, and muscles in the leg are named according to what bone they are near (e.g.

tibialis anterior The tibialis anterior muscle is a muscle of the anterior compartment of the lower leg. It originates from the upper portion of the tibia; it inserts into the medial cuneiform and first metatarsal bones of the foot. It acts to dorsiflex and invert ...

are near the tibia). So the artery that runs near the smaller leg bone had two names: the ''peroneal artery'' and the ''fibular artery''. The term ''fibula'' eventually became the standard name for the bone, but many of the related arteries, muscles, and nerves are still called by the Greek derived name ''peroneal''. The

Terminologia Anatomica ''Terminologia Anatomica'' (commonly abbreviated TA) is the international standard for human anatomy, human anatomical terminology. It is developed by the Federative International Programme on Anatomical Terminology (FIPAT) a program of the Inter ...

, the international standard for anatomical nomenclature, states that both ''fibula'' and ''perone'' derived names are acceptable, but lists the ''fibula'' derived names as the preferred terms. Like ''fibula'', the ''perone'' (pronounced pair-uh-knee) means ''pin of a brooch'' or ''buckle''.
