7 tarsal bones: talus, calcaneus, navicular, cuboid, medial cuneiform, lateral cuneiform, and intermediate cuneiform
5 metatarsals: make up the mid-foot
14 Phalanges: make up the toes |

| formed by talocrural joint and the subtalar joint. Ankle is stronger medially rather than laterally because of the bone and ligamentous structures present. Ankle is structurally weakest in regards to musculature. 13 major muscules support and allow movement in ankle and lower leg. Also in the foot and toes. |

help to make the ankle structurally very strong; ankle is still susceptible to injury in althletics due to the stresses placed upon it. Ligaments help to provide stability both medially and laterally.
*Ligaments are named for the bones they connect.
