The foot (plural feet) is an anatomical structure found in many vertebrates. It is the terminal portion of a limb which bears weight and allows locomotion. In many animals with feet, the foot is a separate organ at the terminal part of the leg made up of one or more segments or bones, generally including claws or nails. The ankle, or talocrural region, is the region where the foot and the leg meet. The ankle incudes three joints: the ankle joint proper or talocrural joint, the subtalar joint, and the Inferior tibiofibular joint. In common usage, the term ankle refers exclusively to the ankle region. In medical terminology, 'ankle' (without qualifiers) can refer broadly to the region or specifically to the talocrural joint. The main bones of the ankle region are the talus (in the foot), and the tibia and fibula (in the leg). The talus is also called the ankle bone.
