The peroneus tertius is an almost completely tendinous structure that originates from the extensor fossa of the distal femur, runs over the cranial aspect of the tibia and inserts, after dividing into two, on the fibular, third and fourth tarsal bones and proximal third metatarsus. <br><br>

It is an important part of the reciprocal apparatus, which mechanically flexes the hock when the stifle joint is flexed.
