===Tibia and Fibula===
===Tibia and Fibula===
As in other species, the tibia bears the weight transferred through the hindlimb and the fibula is rudimentary.
====Tibia====
The proximal articular surface of the tibia is roughly triangular in shape. An '''intercondylar eminence''' prodtrudes from the centre of the triangle. The apex of the triangle is formed by the '''tibial tuberosity''' where the three tendons of insertion of the ''quadriceps'' muscle attach. The craniolateral border has a deep '''extensor groove''' and the base of the triangle (faces caudally) is divided by a '''popliteal notch'''. The popliteal notch continues to form a prominent '''popliteal line''' on the caudal surface which provides a attachment for the ''popliteus'' muscle. At the distal end of the tibia are two grooves separated by a ridge known as the '''cochlea''', which is bounded by medial and lateral malleoli on each side. The lateral malleolus is formed, developmentally, from the distal end of the fibula.
====Fibula====
The head of the fibula articulates with the lateral condyle of tibia. It tapers distally to end approximately halfway down the tibia.
