Third metatarsal bone in the context of "Metatarsal bones"

The second metatarsal bone is a long bone in the foot. It is the longest of the metatarsal bones, being prolonged backward and held firmly into the recess formed by the three cuneiform bones. The second metatarsal forms joints with the second proximal phalanx (a bone in the second toe) through the metatarsophalangeal joint, the cuneiform bones, third metatarsal and occasionally the first metatarsal bone.

The fourth metatarsal bone is a long bone in the foot. It is smaller in size than the third metatarsal bone and is the third longest (and smallest) of the five metatarsal bones. The fourth metatarsal is analogous to the fourth metacarpal bone in the hand

As the four other metatarsals bones it can be divided into three parts; base, body and head.The base is the part closest to the ankle and the head is closest to the toes. The narrowed part in the middle is referred to as the body or shaft of the bone. The bone is somewhat flatten giving it two surfaces; the plantar (towards the sole of the foot) and the dorsal side (the area facing upwards while standing). These surfaces are rough for the attachment of ligaments. The bone is curved longitudinally, so as to be concave below, slightly convex above.
