Talus
- Features neck, head, and trochlear surface, which articulates with tibia of leg; lateral and medial tubercles border the groove for the tendon of flexor hallucis longus.

Additional Foot Bones
Metatarsals

Phalanges

- Middle phalanges
- Distal phalanges
- Digits 2-5 have all three phalanges, digit 1 has only proximal and distal phalanges.
Arches of the Foot
- Created by the bones of the foot, and are supported by ligaments and tendons, which respond to changes in weight load during bipedal movement.
Medial
- Arises on the calcaneus, extends to the metatarsals 1-3; the talus is its keystone bone
