This element is only present in the four lateral digits. These are very short elements that are typically broader than their proximal namesakes. They have concave proximal ends and convex distal ends with very shortened, constricted shafts.

Etymology

Phalanges, plural for phalanx, is a Greek term that referred to a line of heavy-armed infantry drawn up in close order to do battle. The parallel digital rays resembled these lines of battle.

Articulations

The middle phalanges articulate with the proximal and distal phalanges.
