The cuboid bone is one of the seven tarsal bones located in the foot. It is situated on the outer side of the foot, between the calcaneus (heel bone) and the fourth and fifth metatarsal bones. The cuboid bone plays a crucial role in maintaining the foot's structure and stability, particularly during walking and running. This bone has a cube-like shape, which is where it gets its name. It helps in forming the lateral arch of the foot and provides support for the weight of the body. Proper functioning of the cuboid bone is essential for overall foot health and mobility.
