Intermediate phalanges

Intermediate phalanges are bones found in the limbs of most vertebrates. In humans, they are the bones of the finger and toe which lie in the middle, between the two wrinkly joints. In most other vertebrates, they have a corresponding place in their limbs, whether they be paw, wing, hoof or fin.

The intermediate phalange is not only intermediate in location, but is also usually intermediate in size among the other phalanges ("finger" bones).
