Lateral ungual cartilage

In horses, the distal phalanx is accompanied on each side by the lateral and medial ungual cartilages of the hoof. There are fibrocartilagenous plates that continue the palmar processes bilaterally. The abaxial surface is convex and the axial surface is concave. Their distal halves are enclosed in the hoof but the proximal borders extend to the middle of the pastern.
