This vessel is a continuation of the anterior tibial. It commences in front of the hock-joint, and passes obliquely outwards beneath the peroneus and the short extensor of the foot, to reach the furrow formed by the large canon and the outer splint-bone, along which it runs until nearing the fetlock-joint, where it passes inwards between the suspensory ligament and the large metatarsal bone, and divides into two branches - the right and left digital arteries. These traverse the sides of the phalanges or pasterns, and are ultimately destined to the foot.
The Posterior Tibial Artery lies deeply situated behind the tibia, and besides furnishing branches to the deep muscles of the leg it also supplies the nutrient vessel of the bone, and furnishes branches to the hock-joint. Finally it divides into the two plantar arteries.
