The distal phalanx is rounded to a point distally. The proximal articular surface has two concavities separated by a ridge. The palmar border meets with the distal sesamoid bone. The dorsal aspect has a marked '''extensor process''', where the common digital extensor attaches. The solar surface has two distinct areas, the more palmar area is the roughened flexor surface and the remainder is smooth, concave and crescent-shaped. The parietal surface of the distal phalanx is that which conforms to the hoof wall. It is rough, porous and has processes on each side heading in a palmar direction. The ungual (collateral) cartilages attach to these processes, they are squarish plates which are palpable above the level of the hoof. They become more fibrous in life and may ossify. | The distal phalanx is rounded to a point distally. The proximal articular surface has two concavities separated by a ridge.
