Cuboid

The Cuboid Bone (os cuboideum) is placed on the lateral side of the foot, in front of the calcaneus, and behind the fourth and fifth metatarsal bones. It is of a pyramidal shape, its base being directed medialward.   Surfaces The dorsal surface, directed upward and...

Lateral Cuneiform bone

Navicular – Foot

The Navicular Bone (os naviculare pedis; scaphoid bone) is situated at the medial side of the tarsus, between the talus behind and the cuneiform bones in front.   Surfaces The anterior surface is convex from side to side, and subdivided by two ridges into three...

Calcaneus

The Calcaneus (os calcis) is the largest of the tarsal bones. It is situated at the lower and back part of the foot, serving to transmit the weight of the body to the ground, and forming a strong lever for the muscles of the calf. It is irregularly cuboidal in form,...

Talus – Astragalus
