Anatomy of the Foot

The foot is the terminal portion of the lower limb, whose primary function is to bear weight and facilitate locomotion. The foot comprises 26 bones, including the tarsal bones, metatarsal bones, and phalanges. The bones of the foot form longitudinal and transverse arches and are supported by various muscles, ligaments, and tendons that allow for flexibility as well as dynamic and static support. The foot has 3 primary arches and multiple ligaments that are essential to its structure. The arches are important in absorbing weight during standing, walking, and running and the ability to adapt to uneven terrain during locomotion.
