The ankle bone, also known as the TALUS, is a small bone located between the TIBIA and FIBULA in the lower leg. It is part of the tarsal bones, which are a group of seven bones that form the ankle joint. The other tarsal bones include the calcaneus, navicular, cuboid, and three cuneiform bones. The SHIN bone, or TIBIA, is the larger of the two bones in the lower leg and connects the knee to the ankle. The FIBULA is the smaller of the two bones and runs parallel to the TIBIA. The TARSI are the five bones that make up the midfoot, and the tali are the two bones that form the heel. Together, these bones form the TARSUS, which is the uppermost part of the foot.
