What bones are part of the pastern joint?

The pastern joint is the articulation between the proximal and middle phalanges. In horse anatomy, the proximal phalanx is P1 (the short pastern bone) and the middle phalanx is P2 (the long pastern bone). These two bones meet to form the pastern joint, allowing bending of the pastern region. The coffin joint, by contrast, is between P2 and P3 (the middle and distal phalanges). So naming P1 and P2 identifies the bones that directly comprise the pastern joint.
