The tibia and fibula are the two bones making up the pelvic limb distal to the patella and femur and proximal to the tarsals and metatarsals. The fibula is a very thin bone in comparison to the tibia. Note the tibial crest, which is unique to the tibia and helps form the "triangular" shape of the bone. Also note the lateral and medial condyles of the tibia, the extensor sulcus, the medial malleolus, and the tibial tuberosity.

On the fibula, note the head, the fibular notch which meets with the tibia, and the lateral malleolus
