Cuboid

The Cuboid (pronounced: /ˈkjuːbɔɪd/) is one of the seven tarsal bones located in the foot. It is situated on the lateral (outer) side of the foot, in front of the calcaneus and behind the fourth and fifth metatarsal bones.

Etymology

The term "cuboid" is derived from the Latin word "cubus" meaning cube, and the Greek suffix "-oid" meaning likeness. This is due to the bone's cube-like shape.

Function

The cuboid bone plays a crucial role in the stability and flexibility of the foot. It helps to control the movement and balance of the foot while walking or running. It also serves as a connection point for several muscles and ligaments, including the peroneus longus and the tibialis posterior.
