Middle phalanges (hand)
The middle phalanges (hand), also known as the intermediate phalanges, are bones located in the fingers. Each intermediate phalanx connects to a proximal and distal phalanx. Each proximal phalanx is jointed to the metacarpal bone located in the palm, while each distal phalanx serves as the tip of a finger, as well as the home of the fingernail. This middle phalanx has two joints, and allows the finger to bend in two places. The intermediate phalanges are unique to fingers. The thumb does not possess such a bone, as it only consists of a proximal and distal phalanx.
