There are 15 bones that form connections from the end of the forearm to the hand, of which 8 are carpal bones that form the wrist. These bones are grouped in two rows that serve different functions. The crux of understanding the elbow lies in understanding the interaction between the elbow, forearm and wrist. Effective use of our hands (a big part of what makes us human), requires stable, painless elbow joints. The elbow bones include the upper arm bone, the larger bone of the forearm, and the smaller bone of the forearm. The elbow is a hinge joint which means that it can bend and straighten out just like a hinge does.
