tibia
The tibia is a large bone located in the lower front portion of the leg. The tibia is also known as the shinbone, and is the second largest bone in the body. the tibia carries a significant portion of the body weight. The distal head of tibia articulates with with the talus forming the upper joint tibiotarsal joint. It is a synovial hinge joint.

Fibula
The fibula is the long, thin and lateral bone of the lower leg. It runs parallel to the tibia, or shin bone, and plays a significant role in stabilizing the ankle and supporting the muscles of the lower leg. Compared to the tibia, the fibula is about the same length, but is considerably thinner. the fibula merely functions as a support for the tibia. The head of the fibula forms the proximal (superior) tibiofibular joint with the lateral edge of the tibia

tarsals
A set of seven irregularly shaped bones. They are situated proximally in the foot, in the ankle area. The tarsal bones of the foot are organised into three rows; proximal, intermediate and distal. The proximal tarsal bones are the talus and the calcaneus. They form the bony framework around the proximal ankle and heel area. Superiorly: Ankle joint – between the talus and the bones of the leg (the tibia and fibula). Inferiorly: Subtalar joint – between the talus and calcaneus. Anteriorly: Talonavicular joint – between the talus and the navicular. The calcaneus lies underneath the talus, and has two articulations: Superiorly: Subtalar joint – between the calcaneus and the talus. Anteriorly: Calcaneocuboid joint – between the calcaneus and the cuboid. The cuboid is the most lateral bone in the distal row, articulating with the calcaneus posteriorly, and two metatarsals anteriorly. As the name suggests, it is shaped like a cube.

there are 2 important joints. The articular at the anterior portion of the lower ankle joint is called the talocalcaneonavicular joint and the posterior of the lower ankle joint is called the subtalar joint and this is where the talux and calcaneous articulate.

metatarsals
similar to the hand the foor has 5 bones that align with phalanges and metatarsals. They are called the first metatarsal, second metatarsal, third metatarsal, fourth metatarsal, and the fifth metatarsal. The first metatarsal is the strongest of the group.Metatarsals are convex in shape (arch upward), are long bones, and give the foot its arch. They work with connective tissues, ligaments and tendons, to provide movement in the foot.
Phalanges
there are 14 total phalanges in the foot 3 in each toe minus and big toe which has 2. The big toe is also called hallux. The medical name for thumb is pollex.
