Tibia and fibula

Human tibia shown as a single robust weight-bearing medial lower-leg long bone in anatomical view, colored pale ivory to off-white or light beige. The broad expanded proximal end forms the tibial plateau with distinct medial and lateral condyles for articulation. The shaft is thick, straight, and sturdy with a slightly triangular profile, a prominent sharp anterior crest along the front, a smooth medial surface, and subtle anatomical ridges along the cortical bone. The distal end is widened with smooth articular areas and forms the medial malleolus projecting downward at the ankle.
