What are the bones in a bats wings?

The bones in a bat's wings are primarily modified versions of the same bones found in human hands. The wing consists of elongated fingers (metacarpals and phalanges) that support the wing membrane, or patagium, which stretches between the fingers and the body. Additionally, bats have a humerus, radius, and ulna in their forelimbs, which help provide structure and support for flight. This unique skeletal structure allows bats to achieve their exceptional flying abilities.
