Bones
Nearly one-fourth of the body's bones are in our feet.
The bones of the feet are:
- Talus – the bone on top of the foot that forms a joint with the two bones of the lower leg, the tibia and fibula.
- Calcaneus – the largest bone of the foot, which lies beneath the talus to form the heel bone.
- Tarsals – five irregularly shaped bones of the midfoot that form the foot's arch. The tarsal bones are the cuboid, navicular and medial, intermediate and lateral cuneiforms.
- Metatarsals – five bones (labeled one through five, starting with the big toe) that make up the forefoot.
- Phalanges (singular: phalanx) – the 14 bones that make up the toes. The big toe consists of two phalanges – the distal and proximal. The other toes have three.
- Sesamoids – two small, pea-shaped bones that lie beneath the head of the first metatarsal in the ball of the foot.
