The lateral tarsal artery (tarsal artery) arises from the
dorsalis pedis
In human anatomy, the dorsalis pedis artery (dorsal artery of foot) is a blood vessel of the lower limb. It arises from the anterior tibial artery, and ends at the first intermetatarsal space (as the first dorsal metatarsal artery and the deep ...

navicular bone
The navicular bone is a small bone found in the feet of most mammals.
Human anatomy
The navicular bone in humans is one of the tarsal bones, found in the foot. Its name derives from the human bone's resemblance to a small boat, caused by th ...
; it passes in an arched direction lateralward, lying upon the
tarsal bones
In the human body, the tarsus is a cluster of seven articulating bones in each foot situated between the lower end of the tibia and the fibula of the lower leg and the metatarsus. It is made up of the midfoot ( cuboid, medial, intermediate, and ...

extensor hallucis brevis
The extensor hallucis brevis is a muscle on the top of the foot that helps to extend the big toe.
Structure
The extensor hallucis brevis is essentially the medial part of the extensor digitorum brevis muscle. Some anatomists have debated wheth ...
and
extensor digitorum brevis
The extensor digitorum brevis muscle (sometimes EDB) is a muscle on the upper surface of the foot that helps extend digits 2 through 4.
Structure
The muscle originates from the forepart of the upper and lateral surface of the calcaneus (in fron ...
; it supplies these muscles and the articulations of the tarsus, and receives the

anterior lateral malleolar and the perforating branch of the
peroneal 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.
Structure
The fibular artery arises from the bifurcation of tibial-fibular trunk int ...

lateral plantar arteries through perforating arteries of the foot.
