- articulation between talus/navicular and calcaneus/cuboid
Medial Longitudinal Arch
- highest of 3 arched of foot
- calcaneus, talus, navicular, cuneiform and 1st three metatarsals
- supports: ligaments-spring ligament and plantar fascia; tendons-tibialis posterior and tibialis anterior
Transverse Arch of Foot
- boney structure: medial, intermediate, lateral cuneiforms and cuboid
- interlocking nature of articulations and extrinsic support/plantar structures

- medial cuneiform, middle cuneiform, lateral cuneiform, cuboid
- navicular and tarsal in next row
What is the function of the peroneal tubercle of calcaneus?
-separates tendons of peroneus brevis and longus
What is the function of the spring ligament?
-supports head of talus and bears a significant portion of body weight
