This article looks at the structure of the foot — including bones, muscles, ligaments, and tendons — and some of the common conditions that affect it.

The feet support the human body when standing, walking, running, and more. They are complex structures with 26 bones. Learn more about foot bones and foot anatomy here.

The 26 bones of the foot consist of eight distinct types, including the tarsals, metatarsals, phalanges, cuneiforms, talus, navicular, and cuboid bones.

We’ll break down the anatomy and function of the upper leg, knee, lower leg, ankle, and foot. You’ll learn about the muscles, bones, and other structures of each area of the leg.
