Fourth Metatarsal Bone

The Fourth Metatarsal Bone is one of the five long bones in the foot, known as the metatarsal bones. It is located in the central part of the foot and is associated with the fourth toe.

Etymology[edit | edit source]

The term "metatarsal" is derived from the Greek words "meta," meaning after, and "tarsos," meaning ankle. This refers to the location of these bones, which are situated after the tarsal bones in the foot.

Anatomy[edit | edit source]

The fourth metatarsal bone is similar to the other metatarsal bones in its anatomical structure. It has a base at one end, a shaft in the middle, and a head at the other end. The base is the part of the bone that connects to the cuboid bone in the foot. The shaft is the long, straight part of the bone, and the head is the rounded end that connects to the fourth toe.

Function[edit | edit source]

The primary function of the fourth metatarsal bone, like the other metatarsal bones, is to provide support and stability for the foot when standing, walking, or running. It also plays a role in the complex process of balance.
