What bones are part of the fetlock joint?

The fetlock joint in a horse is the metacarpophalangeal joint formed where the cannon bone (third metacarpal) meets the proximal phalanx (long pastern). Two proximal sesamoid bones sit at the back of this joint, acting as pulleys and helping to distribute load and guide the tendons. So the bones involved in the fetlock joint are the cannon bone, the long pastern, and the proximal sesamoid bones. The other options include bones from other parts of the limb or joints not part of the fetlock (for example, joints further up the limb or the coffin joint behind the pastern), which is why they aren’t correct.
